2013 Top 10 Construction Projects

UDOT Logo udot.utah.govWith summer fast approaching, we would like to share our top 10 road construction projects for 2013.

While there will not be as many large road projects in 2013, there will still be more than 150 construction projects statewide that will require drivers to plan ahead. This season, we will continue to perform maintenance on our roads and bridges to ensure they remain in good condition and last as long as possible.

We will also use innovative technology to improve traffic flow with the installation of the fifth and sixth diverging diamond interchanges (DDI) as well as the 11th continuous flow intersection (CFI) in the state.

The following is a list of the top 10 projects statewide in 2013:


  1. I-80 Drainage Pipe Replacement, Salt Lake County. Crews will install new drainage pipe in Parleys Canyon to replace the existing system. Drivers should expect lane closures throughout the summer. Project completion is estimated for December 2013.
  2. I-15, South Payson Interchange to Spanish Fork River. This summer, crews will work to widen seven miles of pavement and bridges on I-15 from the South Payson Interchange to the Spanish Fork River. Most of the work will take place in the freeway median, and construction is expected to be completed by the end of the year.
  3. Southern Parkway, St. George. The Southern Parkway is a 33-mile project that will eventually become an eastern belt route for Washington County. Currently, eight miles are complete from I-15 to the new St. George Airport. Construction continues this spring and summer to extend the new highway another eight miles.
  4. S.R. 193, Davis County. Crews are extending state Road 193, the Bernard Fisher Highway, from 2000 West (S.R. 108) on 200 South in West Point to 700 South and State Street (S.R. 126) in Clearfield. Work scheduled this spring and summer includes earthwork, utility relocations, drainage and sound wall construction. Temporary road closures or blockages may happen from time to time on local streets and trails.
  5. I-15, St. George Boulevard DDI Interchange Reconfiguration. Reconstruction work will take place on the existing diamond interchange to install southern Utah’s first diverging diamond interchange. Work is expected to begin this summer and finish by the end of the year.
  6. U.S. 89/91 Repaving, Sardine Summit to S.R. 23, Cache County. The second phase of work continues from last season’s repaving of U.S. Highway 89/91. Maintenance work will take place from Sardine Summit to Wellsville to maintain a smooth road surface and prolong the life of the roadway. Daytime lane closures will be taking place throughout the summer.
  7. I-15, 1100 South (U.S. 91) DDI Interchange, Brigham City. Work to build the first diverging diamond interchange in northern Utah will begin this summer on the I-15 and 1100 South interchange in Brigham City. Traffic may be redirected around the project throughout its duration, but crews will work to minimize delays. This project is expected to be complete next summer.
  8. U.S. 89 Improvements, Orem to Pleasant Grove. Crews will make several improvements to State Street between Orem and Pleasant Grove this summer. The road will be widened to seven lanes, repaved with new asphalt, and upgraded with curb, gutter and new sidewalks in various locations. The project will improve traffic flow and reduce congestion in the area. Drivers should expect minor traffic delays due to lane restrictions.
  9. Bangerter Highway, 13400 South CFI Installation, Salt Lake County. Construction of a new continuous flow intersection (CFI) on Bangerter Highway at 13400 South will improve the flow of traffic in this fast-growing section of the Salt Lake Valley. Lane restrictions will occur throughout the project but will take place during non-commute and nighttime hours. Construction will be completed this year.
  10. I-215 Maintenance, S.R. 201 to North Temple, Salt Lake City. A heavily traveled section of I-215 will undergo concrete repair this summer for approximately two months with occasional lane and ramp closures. Work will take place during overnight and non-commute hours to minimize delays.

We are committed to continually looking for new opportunities to proactively communicate with the public about our projects. The following are available tools to plan ahead and stay informed about our projects:

  • “UDOT Traffic” App — The UDOT Traffic app delivers critical traffic information directly to drivers by incorporating the best and most up-to-date information from the UDOT Traffic Operations Center, including real-time traffic conditions, construction alerts, crash information and road weather conditions. The app now features TravelWise alerts, which provide us with a direct way to communicate with drivers at critical times. The alerts proactively communicate major traffic incidents, event traffic warnings, weather-related road conditions, construction and air quality information so drivers can plan ahead, reduce delays and arrive safely at their destinations. UDOT Traffic is free and available for download in the Apple App Store and Android Market for tablets and phones.
  • Interactive UDOT Traffic Website — The website features an interactive map identifying the locations of UDOT projects statewide. Additional information is provided for each project, including the construction schedule, expected travel delays and the project benefits. The website can be accessed from
  • UDOT’s Twitter Account — Follow UDOT’s Twitter feed at to receive regular updates on road construction and traffic conditions.
  • 2013 Road Construction Guide – The guide is available for download and includes a list of the 10 most significant projects.

UDOT Traffic Management Division Maintenance Crew Creating an Asset Management Plan

Note from administrator: Besides Lisa Miller this post also contains information written by Brad Lucas. Both Brad and Lisa work in the Traffic Management Division.

Preserving Utah’s road infrastructure is a critical component of UDOT’s Strategic Goals. The UDOT Traffic Management Division is creating an Asset Management Plan for devices within the Advanced Traffic Management (ATMS) System to help UDOT to continue its proactive maintenance of field devices. Devices the plan will take into account include traffic cameras, variable message signs (VMS), pavement detectors, road/weather stations, etc. An Asset Management Plan can also help to identify funding sources for new and replacement equipment.

Traffic Camera RepairWith over 1800 devices throughout the state and over 1800 miles of fiber optic cable to maintain, each of UDOT’s 16 technicians are responsible for over 100 devices. “Our staff is responsible for troubleshooting, corrective maintenance, ordering replacement parts and device installation. With a statewide system to maintain, some of these tasks can take up to a half day to complete per device,” said Brad Lucas, UDOT ITS Systems Engineer. Long term performance of the system relies on good maintenance now and allows for easier expansion and replacement in the future.

UDOT’s strategy must have a statewide approach and address long term system growth and health. “Some components of our infrastructure are aging, and good system maintenance helps to extend the life of the equipment,” said Lucas. UDOT’s Asset Management Plan will research the best and most meaningful use of public resources when budgets are tight and demand for data from field devices is high.

UDOT currently achieves between 85% and 90% of all system devices are fully operational. An Asset Management Plan will help to raise those percentages, identify life cycles for equipment replacement and strategically manage the equipment to ensure its long-term performance. Keeping the equipment operational helps to manage traffic more efficiently, and having reliable statistics on how the system is performing is an important metric for how public funds are spent.

Utah DOT Leveraging LiDAR for Asset Management Leap

This guest post was written by Philip Ellsworth for industry magazine LiDAR News. Philip is a consultant working with UDOT’s Consultant Services Division.

Mandli Vehicle

UDOT recently brought on Mandli Communications to undertake a groundbreaking inventory of Utah State Routes, the Mandli vehicle is equipped with multiple sensors, including a Velodyne LiDAR sensor.

In a world where LiDAR has revolutionized movie making, the Utah Department of Transportation is employing this impressive technology on a groundbreaking data collection project that will set the stage for vastly improved asset management — not just at UDOT, but across the country. After advertising a one-of-a-kind Request for Proposals (RFP) in the fall of 2011, UDOT has recently entered into a contract with Mandli Communications to gather, identify, and process a wide variety of roadway assets along its entire 6,000+ center lane miles of State Routes and Interstates. With the winning bidder (Mandli) proposing to use mobile LiDAR as its primary technology on the project (along with an array of other sensors), this UDOT contract may very well be the first of its kind in technological magnitude and scope.

In the beginning, the project was a simple effort to update an ongoing program where a contractor had been hired to gather roadway distress data for the Department. It was not long before the initially small UDOT team began to see that there was more potential to their efforts than just pavement distress data. With the leadership of Stan Burns, Director of UDOT Asset Management, they expanded their efforts to pull in other groups, asking everyone along the way, “What data can your division use to enhance your asset management decisions through a simplified collection effort?” It was soon discovered that some divisions had been duplicating efforts, potentially costing the Department precious resources; quickly a dynamic and diverse team began to form.

Signalized Intersection Data

The UDOT project includes an inventory of numerous roadway assets, including signalized intersections and some pavement marking, using LiDAR imaging as a backbone of the project.

A goal, established to “deploy state of the art collection methods to improve and develop rigorous safety, maintenance and preservation programs” became a key motivator to UDOT embarking on this project. Beyond this goal, it is clear that UDOT believes that the ability to make efficient asset management decisions is entirely dependent upon the accuracy and credibility of the available data. Confidently knowing the full details of UDOT’s multi-billion dollar infrastructure makes a better decision-making environment for leaders. And with safety at the forefront of UDOT’s and the public’s mind, it is critical to have the most dependable data possible in order to make potentially lifesaving decisions.

Mandli has completed the first phase of the project – data gathering – and is in the process of the second phase of the project – post processing and data delivery. Mandli proposed to gather both the positive and negative directions of data on Utah roads in 2012 and then come back in 2014 and update the data sets. The UDOT Roadway Imaging and Inventory program requires the vendor to gather no less than a dozen different roadway assets including roadway distress data, surface areas, lane miles, number of signs, ROW images, vertical clearances, and more with each of those categories broken down even further into subcategories ranging from condition data to GPS data, etc.

Sensors on the UDOT Mandli flagship vehicle include a Velodyne LiDAR sensor, a laser road imaging system, a laser rut measurement system, a laser crack measurement system, a road surface profiler, a position orientation system, and more – certainly making it one of Mandli’s most advanced asset gathering vehicles in their fleet.

While UDOT acknowledges a few hiccups along the way, the Department is excited to see the final results, expecting that the scope of the data being collected in and of itself will be better than what is available today. However, expectations of better data simply due to the size of the project hasn’t stopped UDOT from getting heavily involved in the Quality Assurance (QA) aspects of the project; aggressively pursuing the accuracy side of the project as well, even requiring a weekly QC/QA update meeting between UDOT, Mandli and their QA partner Stanley Consultants. This QA effort, combined with tight data tolerances, is expected to net UDOT a data set that meets one of their top original goals to “Gather the most data pertaining to roadway condition, location and roadway assets in an economical way, while maintaining a high level of accuracy and quality.”

UDOT believes that the use of LiDAR is actually providing more return on their investment, helping them meet their goal of gathering as much data as possible in an economical way, while maintaining a high level of accuracy and quality.

UDOT believes that the use of LiDAR is actually providing more return on their investment, helping them meet their goal of gathering as much data as possible in an economical way, while maintaining a high level of accuracy and quality.

While this project’s level of data collection is certainly possible using more traditional, ’boots on the ground‘ methods, UDOT believes that adding the use of LiDAR is actually providing more return on their investment. In the beginning, there was some hesitancy on the part of some involved, with some even expressing doubt that an endeavor of this magnitude could ever achieve its goals, or at least not without a technology such as LiDAR to complete it. The team moved forward anyway, knowing that an effort
was needed to gather the most data they could in the most cost-effective way possible – in order to increase their ability to make asset and safety management decisions with more confidence. They were truly convinced from the beginning that the effort to cobble together a diverse team would benefit each division through an “economies of scale” approach to procurement. When it was found that LiDAR was within reach, and had even been proposed by the winning team, the excitement level for the project increased exponentially. This alone, UDOT team members believe, has kept team members vigorously involved, creating a collaborative effort that even some naysayers now applaud.

UDOT team members have learned that collaboration is important because of its affect on the DOT’s ability to integrate their asset data in a meaningful way. Having multiple sets of similar data dispersed in disparate ways leads to duplication of efforts, an increase in the loss of data integrity, and an increased risk for data to become obsolete more quickly than if the data can be integrated and accessed through a collaborative effort. This project is proving to UDOT that integration is not only necessary in today’s asset management world, but that it is indeed possible.

UPLAN Website

UDOT’s UPLAN network, distributed through an ArcGIS platform is helping to get their roadway data into as many hands as possible, including the public.

One tool in UDOT’s bag of integration innovation is their UPLAN planning network platform, which has found itself in a symbiotic relationship with the UDOT Roadway Imaging and Inventory program. UPLAN is distributed on an ArcGIS platform, in conjunction with UDOT’s existing Oracle-based systems. Frank Pisani, UDOT’s GIS Manager says that it was initially developed as an internal planning tool but has quickly become UDOT’s enterprise-wide attempt to disseminate its vast database of information in a user-friendly environment, accessible online at The Roadway Imaging and Inventory project will help UPLAN by supplying it with a large amount of accurate information, while UPLAN will help the Roadway Imaging and Inventory project by becoming another portal by which the data can be distributed. This creates a scenario where not only will UDOT managers and staff be anticipating the project data, but the public can now anticipate the opportunity to experience the data as well.

No fewer than eight managers from various divisions, both inside and outside UDOT (including asset management, structures, traffic & safety, GIS, technology services, motor carriers, and more) have been collaborating on this UDOT project for well over a year. And now, with the project in full swing, these eight divisions are continuing to work together, while bringing others into the project along the way.

One group of experts that has been increasingly interested in the project are UDOT preconstruction engineering teams – those who spend a majority of their time designing UDOT roads, bridges, and other infrastructure. The mobile LiDAR point cloud has proven extremely intriguing to these preconstruction groups and as a result there is a clear desire within UDOT to discover its untapped potential. Preconstruction engineering teams are even investigating the possibility of getting high enough accuracy out of the LiDAR point cloud to be used in some preliminary design scenarios. For this endeavor, they’ve turned again to the LiDAR industry of professionals and are working with consultants, including Virtual Geomatics, to develop methods to enhance the accuracy of the LiDAR point cloud through a calibration process. Early efforts appear promising, with indications of getting to an average accuracy level of +/- 3 cm when using control points contained in the point cloud data.

Another group within UDOT that has increasingly expressed interest and favor for this project are members of the Department leadership and management, not only from those close to the project but others as well. UDOT indicates that a paradigm shift may be occurring within the DOT where employees in leadership and beyond are more commonly asking spatially-oriented questions, which fosters an environment where the value of data integration and data accuracy is not just recognized but demanded.

UDOT may well be showing that system-wide mobile LiDAR is within reach for DOT's across the nation.

UDOT may well be showing that system-wide mobile LiDAR is within reach for DOT’s across the nation.

Even with the long awaited MAP-21 legislation driving DOT’s across the nation to re-think their asset management programs, through its requirement that each state develop a risk-based asset management plan for the National Highway System, UDOT has found a way to stay at the leading edge of another transportation industry leap. And they’re clearly showing that system-wide mobile LiDAR is within reach for DOT’s across the nation.

Copper Wire Theft

Wire Theft Photo 1

Thieves used a golf club shaft to locate the copper wiring. They dug it up, cut it, and tried to pull it out by attaching it to a vehicle.

Driving in the dark lately? You may have noticed the lights are out along some sections of major interstates, like I-15, I-80, and I-215. But don’t blame the power company or burned out light bulbs…the real culprits are thieves who are in the business of stealing copper wire.

When you and I drive past the big light posts on the freeway, we might not think twice about the copper wiring that powers high mast and interchange lighting. But to some, the junction boxes next to the posts are a gold mine waiting to be found. To uncover the copper wiring and pull it out, thieves have used everything from shovels and trucks…to golf clubs and horses.

To combat their creativity, we’ve got to get a little creative ourselves. Led by Richard Hibbard, UDOT’s State Lighting Maintenance Crew (Mike Bishop, Todd Wright, John Garcia, Walter “Woody” Wood, and Brandon Clark) focuses on the hardest hit areas and the biggest targets.

Wire Theft Photo 2

The lighting crew has tried relocating and burying boxes as a method of theft deterrent, but in this case, the thieves managed to locate the box and dig it up.

The crew is now moving junction boxes away from the light posts and burying them randomly, making the boxes more difficult for thieves to find. (Don’t worry, we’ve got a locator ball inside so our own guys know where they are.) The crew is also welding handhole covers onto poles, filling some boxes with concrete, and adding rebar to others to make it harder to chip the concrete away.

Despite our best efforts, thieves are still getting to some of those areas and they’re hitting new locations seemingly every week. Hibbard says some of the hot spots are I-80 near Stansbury Park, I-215 at 700 North and 2100 North, I-15 at 600 North, and I-215 at I-80. He says, “I- 215 at I-80 is just a mess. If anyone wants to know why those lights are out it’s because half the wiring is gone.”

In fact, the amount of copper wire that UDOT has had to replace in just the past two years is staggering. Since February 2011, crews have replaced 110,000 feet of copper wire in Region 2 alone.

Wire Theft Photo 3

Sign structures are fair game with wire thieves. Here they have cut wire in a structure-mounted disconnect box and pulled it out through the ground-level junction box.

They suspect there’s another 75,000 feet missing they haven’t gotten to yet. And the situation does not appear to be improving. In January 2013, thieves made off with 15 hundred feet of copper wire from just one location.

Metal recyclers pay about $2.75-$3.00 per pound for unstripped wire, so a thousand feet of stolen wire would net someone anywhere from $300 to $700. Unfortunately, it costs a lot to replace that wire, and taxpayers are footing the bill. In the past two years, nearly $450,000 of materials and man hours has gone into replacing stolen copper wire. That’s enough money to pay for 26,000 feet of new cable median barrier.

Something needs to change, but what can we do? The answer is keep your eyes open. Hibbard says, “If you see anyone that appears to be working on lighting, someone should be asking questions.” And he means anyone. If you see a guy on a bike digging near a light post, a car pulled off the side of the freeway, or even someone in an orange vest poking around a junction box…be suspicious.

Hibbard suspects many of the thieves are electricians or others who know what they’re doing and look professional. He thinks some thefts may be happening during the day, but most happen at night. “The most suspicious thing is just any time you see a car parked on the side of the road, especially at night. I always find myself wondering what’s going on there.”

If you suspect copper wire theft is underway, but you’re not quite sure, you can always call the TOC and they’ll be able to find out if there’s legitimate work going on in that location.

Wire Theft Photo 4

The lighting crew welded a metal plate over a handhole, but in this case the thieves were able to bend it enough to get to the wire.

If you’re positive there’s a theft underway, just call the police. Let’s put the thieves behind bars, because after all, it’s our taxpayer money they’re stealing.

Wire Theft Photo 8

Thieves will attempt to chip out concrete caps within a box, but rebar will prevent the concrete from “chunking,” making removal far more difficult.

Wire Theft Photo 5

This is an example of a theft-deterring junction box lid. The polymer concrete has a steel plate backing and is attached to the box with security bolts. However, this hasn’t stopped someone from attempting to chip out a bolt as is evident on the lid surface.

2013 Strategic Direction — Part 1

This is the first part of a 4 part series about the 2013 Strategic Direction. Please also check out Part 2: Optimize Mobility, Part 3: Zero Fatalities, and Part 4: Strengthen the Economy.

After a record breaking construction year, with more than 200 projects completed, worth just over $3 billion, what is in store for UDOT in 2013? The newly completed 2013 Strategic Direction and Performance Measures highlights accomplishments by the department in 2012 and introduces goals for 2013 and the coming years.

Key to the Strategic Direction document are the UDOT Strategic Goals. These goals ensure that we focus our efforts and capital on the most important activities. This year we have revised our goals, which include:

  • Preserve Infrastructure
  • Optimize Mobility
  • Zero Fatalities
  • Strengthen the Economy

Details on each goal will be provided in a four part series, beginning with:

Preserve Infrastructure

Preserving Utah’s multi-billion dollar investment is the single largest expenditure year to year within UDOT. Keeping the state’s bridges and pavement in good condition is the most effective way to extend the life of the transportation system. This is accomplished by applying well-timed preservation treatments to roads, and addressing critical needs first. By applying a combination of routine maintenance, preservation and minor and major rehabilitation projects, UDOT is able to utilize limited funding to maximize the pavement condition.

In 2012:

  • More than 100 preservation and rehabilitation projects were completed,
  • Approximately 350 miles, or six percent of the system, received a specific preservation or rehabilitation treatment,
  • Six critical bridges were replaced,
  • Eighty-four new bridges were built by capacity-driven project,
  • Two pedestrian bridges were built,
  • Bridge preservation and rehabilitation activities were performed on more than 170 bridges.

Please also check out Part 2: Optimize Mobility.


UDOT marked two significant milestones as it celebrated the completion of the largest road construction projects in Utah history on Saturday, December 15 with the opening of the Utah County I-15 Corridor Expansion (I-15 CORE) and 15 miles of the Mountain View Corridor (MVC) in Salt Lake County.

“We have delivered the World Series and the Super Bowl all in one day,” said UDOT Executive Director John Njord.

Local leaders, including Governor Gary Herbert, House Speaker Becky Lockhart and Senator John Valentine, joined UDOT in cutting the banner on the record-breaking I-15 CORE project Saturday afternoon. More than 100 people braved the chilly December weather to join the festivities. Refreshments including hot chocolate, hot dogs and special I-15 CORE sugar cookies were available to say thank you to the public for their patience throughout construction.

“Hear the noise. That’s the sound of progress,” Herbert said, as cars and trucks passed underneath the Sam White Bridge on I-15. “That’s the sound of commerce, that’s the sound of a state that’s really going in the right direction.”

Construction on I-15 CORE was finished in an unprecedented 35 months, making it the fastest billion-dollar public highway project ever built in the United States. The project came in $260 million under budget.

Saturday’s celebration was held on the Sam White Bridge in American Fork, the site of one of the project’s greatest achievements. In March 2011, UDOT moved the bridge — the longest two-span bridge to be moved by self-propelled modular transporters
(SPMTs) in the Western Hemisphere — into place over I-15 in one night.

“The technology to move the Sam White Bridge into place in hours instead of months is indicative of all the work that took place on this project” to complete it quickly and keep traffic moving, Njord said.

I-15 CORE reconstructed 24 miles of freeway from Lehi to Spanish Fork, with two additional freeway lanes in each direction.

Earlier that day, snow flurries didn’t deter over 200 runners who bundled up in their winter gear to attend the MVC opening celebration, which featured a 5K Polar Bear Fun Run to give members of the community an opportunity to enjoy the road before it opened to motorists.

“It looks like Christmas to me,” said Governor Herbert as he spoke to the chilly, but upbeat crowd.

Runners were entertained by music courtesy of the Copper Hills High School Marching Band, stayed warm with the help of hand warmers and MVC beanies and enjoyed holiday treats, hot cider and hot chocolate provided by the project’s contractors.

Representative Wayne Harper and West Jordan Mayor Melissa Johnson also addressed the audience and thanked UDOT for their continued innovation and partnership in developing this vital roadway.

The current phase of MVC is 15 miles long and features two lanes built in each direction from Redwood Road (at approximately 16000 South) to 5400 South, with signalized intersections where future interchanges will be located.

To meet projected transportation demands in the year 2030, future construction will build out the remainder of the corridor by adding interchanges and inside lanes to achieve a fully functional freeway that will connect with I-80 in Salt Lake County and I-15
in Lehi.

Construction funds have been identified to extend MVC from 5400 South to 4100 South in the next few years.

The roadway also features 15 miles of trails adjacent to the corridor, 9 miles of paved bike lanes and UDOT’s first radar activated bike turn signal.

“The vision for the Mountain View Corridor came from the communities in Western Salt Lake County,” said Project Director Teri Newell. “UDOT is proud to make this vision a reality and provide these communities with a new transportation solution.”

MVC provides increased mobility, but will require motorists to adjust their driving patterns and learn how to navigate a new one-way roadway, as this initial phase is similar to a divided highway with one-way northbound and southbound roadways. Signs
are posted along the corridor and at each intersection to help motorists adjust to the new traffic patterns. UDOT has also produced a navigational video to teach motorists how to drive on the new roadway.

Governor Herbert touted the success of both the I-15 CORE and MVC projects, highlighting their importance state. “This is about economic development. If you want a state to thrive economically, you’ve got to have a transportation system that works,” said Herbert.

Why do asphalt roads deteriorate? Sometimes the causes of road deterioration are easy to determine and sometimes the causes can remain a bit of a mystery.

Some common causes of deterioration include:

Traffic – heavy truck and automobile traffic causes wear and rutting over time.

Water – water that seeps under the pavement and makes the earth underneath soft. The freeze-thaw cycle causes damage when water seeps into the pavement, freezes and expands, then melts. Over time, the freeze-thaw cycle can break pavement.

Erosion – water can erode slopes and excavate under roads causing indentations and cracking.

Time and sunlight – UV light ages asphalt over time.

Researchers theorize that water vapor condenses underneath the paint leading to damage to the pavement.

Pavement preservation techniques, including surface treatments like slurry sealing, crack sealing, micro surfacing, and help preserve asphalt roads.

One less known cause of pavement deterioration is pavement markings. A UDOT Research project looked at 13 areas around the state, where pavement markings and deterioration had occurred together, to determine if the markings caused deterioration.

Researchers carefully examined each area, making note of all distresses. Pavement markings were found to be significant contributors to pavement deterioration in some cases.

Researchers theorize that water vapor condenses underneath the paint leading to damage to the pavement in the form of raveling or de-bonding. Cracking near the pavement markings also seem to indicate that paint causes stresses that cause cracks that can lead to more damage. Laboratory tests have not yet confirmed the theories.

Selecting the right preservation treatment for the right pavement condition, along with proper production and placement helps eliminate the deterioration that seems to be caused by pavement markings. UDOT has discontinued the use of some pavement treatments that allows water vapor to become trapped between paint and the pavement surface.


Innovation touched every aspect of the I-15 CORE project from construction to communication. While massive structures were built nearby then moved into place, communication experts were devising new ways to inform the public about how to avoid construction related delay.

This post is the second of two posts that detail how combining social media and traffic management tools helped keep traffic moving. The posts are based on a presentation given by Geoff Dupaix, Public Involvement Manager on the project. Missed the first post? Read it here.

“Our project communications team did an outstanding job in finding creative, innovative approaches to keep the public up to speed on the latest construction news related to the project,” says Nile Easton, Communications Director for UDOT. Social media, traffic reports and paid advertisements were used to inform the public about travel through the I-15 CORE construction zone. Two examples illustrate the success of the communication efforts in reducing delay during critical points in time.

No post-game problems!

BYU football games typically draw more than 60 thousand attendees to the campus. That influx of traffic creates delay on I-15 and surrounding streets and requires close collaboration among BYU, police and traffic signal engineers from Orem and Provo.

This graph illustrates how letting the public know about anticipated delay due to construction can affect driving behavior. The PI team asked fans to stay in the Provo area after the game to avoid a heavy influx of traffic. The red line represents an even flow of traffic entering the freeway.

PI and MOT teams anticipated heavy attendance at the BYU vs. Wyoming game that coincided with a ramp closure that eliminated one option for drivers leaving the game. Under normal circumstances, traffic peaks two hours following a game. With the additional ramp closure, PI and MOT team members worried that even more delay could occur. A goal of reducing traffic by 10 percent was set in order to keep traffic moving onto I-15 following the game.

The PI team devised specific messages to the public aimed at preventing traffic entering the freeway all at once after the game. The messages, delivered by Tweets and KSL traffic reports, asked fans to stay in the Provo area after the game to eat, watch a movie or shop. Traffic volume was reduced as a result of the communication effort.

After the game, BYU officials became “true believers” in the ability of the PI-MOT team to provide information and options to the public, according to Geoff Dupaix, a PI Coordinator on the project. “That’s a credit to this team.”

Practice makes perfect

After 60 closures, the PI-MOT team was accomplished in helping the public avoid delay. However, the last full closure posed an additional challenge. A full overnight closure of I-15 was needed to set a bridge girder. The only identified alternate route was a 7 mile detour. The PI-MOT team needed road users to avoid that area of I-15 or face delays.

Messages about the closure and alternate route were conveyed to the public, and PI-MOT team members monitored traffic flow and volumes. Within minutes before the closure, “volume disappeared,” says Eric Rasband, I-15 CORE MOT Manager. The public “became a true partner in our closure.”

Lessons learned

The level of cooperation and successful outcomes resulted in strategies that can be tailored for use on a project of any size:

  • Leadership should set PI and MOT goals, and PI and MOT requirements should be set in tandem.
  • Where possible, set up a mini TOC to monitor traffic moving through the project.
  • Establish a planning and approval process that involves all relevant parties, including project UDOT, the contractor and stakeholders.
  • Set realistic goals for reducing traffic volume and define expectations.  It may not be possible to eliminate all the inconvenience of road construction, but good PI strategies can make traveling through the construction zone much easier.
  • Ask four critical questions before each closure or traffic event: First, what are the current planned traffic conditions and challenges? Second, how do we want driving behaviors to change to meet those challenges? Third, what messages will most effectively affect that change? And fourth, what tactics can be used to communicate those messages, and who should be the target of those messages?

Stakeholder feedback indicates the PI-MOT communication strategies worked:

Today and tomorrow, two posts will detail how combining social media and traffic management tools helped keep traffic moving.  The posts are based on a presentation given by Geoff Dupaix, Public Involvement Manager on the project.

I-15 is Utah County’s only continuous north-south corridor and serves over 120 thousand trips per day. Keeping lanes open and minimizing delay through the corridor during construction was no small task.

Combining two important functions, maintenance of traffic and communication, helped keep traffic moving during I-15 CORE freeway re-construction.

MOT plans detail how traffic is managed during construction projects.  Keeping traffic moving through and around road construction is critical; drivers need clear signs and safe, easy to understand traffic control devices that delineate full closures, alternate routes and lane reductions.

Public Information experts communicate with road users about MOT, and suggest ways to avoid construction related delay. Close collaboration between the PI and MOT teams on the I-15 CORE project was an effective way to inform road users about construction and also keep traffic moving though the corridor.

Communicators on the I-15 CORE project have set new standards for keeping the public informed by using social media, especially Twitter, extensively.

I-15 is Utah County’s only continuous north-south corridor and serves over 120 thousand trips per day. Keeping lanes open and minimizing delay through the corridor was no small task. The project faced challenges including major planned events overlapped with full ramp closures.

Big public events, like concerts or football games, increase traffic volume that can cause delay, making PI efforts critical to maintaining traffic mobility. On a major construction project, good communication with the public can help prevent gridlock.

MOT and PI teams collaborated very closely throughout the project. The teams met often and well in advance of planed closures or big events to discuss and problem-solve. The two teams even moved into adjoining offices to make collaboration more convenient.

Using the proper tools

The I-15 CORE team accessed Traffic Operations Center tools to set up a mini TOC. Camera views specific to the project and traffic volume data gave PI and MOT teams the ability to observe traffic in real time. When crashes or other incidents occurred, help could be dispatched immediately. The PI and MOT team could also observe and direct traffic to less-busy corridors.

Camera views specific to the project and traffic volume data gave PI and MOT teams the ability to observe traffic in real time.

The PI and MOT teams used traffic volume data to set goals for reducing traffic volume during upcoming events or MOT changes. The PI team planned messages that informed the traveling public about anticipated delay and gave options to help road users make good travel decisions. For example, messages would suggest leaving early, taking an alternate route or using an alternate exit. Social media, especially Twitter, was used extensively.

Tweeting traffic information turned out to especially useful for road users. “We got it down to a science,” Dave Smith, Public Information Manager for the project. The PI team was able to affect behavior in a very short time and actually observe traffic divert to under-served corridors based on tweets.

“It was not the number of our followers,” that made the effort successful, according to Smith; traffic reporters who followed the I-15 CORE Tweets passed along that information to their followers as well.

How did the close collaborative effort work? Check back to see tomorrows post detailing two examples and feedback from stakeholders.


UDOT Motor Carriers Division has the responsibility of making sure oversize loads are routed properly. 

Thousands of times times each year, oversize loads travel on Utah highways and arterials. Routing big loads properly protects the traveling public and UDOT’s roads and bridges.

Routing big loads properly protects the traveling public and UDOT’s roads and bridges.

Some of the loads are so big that passing over or under bridges puts those structures at risk. UDOT’s Motor Carriers Division defines the routes for super-sized loads in order to protect those important assets. “Our mission is to protect and preserve the highway infrastructure, while enhancing safety for the motoring public” says Adam Anderson Supervisor for the Superload Coordination Team. Structures and highways cost millions of dollars to build, “we want to have them last a long, long time.”

The Motor Carrier Division utilizes an online permitting system that helps simple the application process for carriers and many permits are issued within minutes. These permits are issued by the Motor Carrier themselves or issued by Ports of Entry Agents throughout the states.

Permits are issued by category according to the size of the load. Extremely large loads, which exceed 14’ high or 14’6” wide or 105’ in length or 125,000 lbs, need to be adjudicated Motor Carrier Specialist, Loads exceeding 15’6” high, 17’ wide or 300,000 lbs needs to be processed by the MCD Super Load Team – Anderson heads the group that includes three other MCD Agents from across the state.

Carriers may also be required to hire pilot cars or police escorts. Oversize loads are also subject to hours of operation limitations to avoid peak traffic.

Routing super loads can be challenging. When construction closes a route to oversize loads, sometimes the defined route can be circuitous or hundreds of miles longer than usual. And, some routes have permanent restrictions due to narrow lanes or other features. New structures that can’t accommodate very tall loads can cut off access through a formerly used route. UDOT routes super loads on state roads first and county and city roads only if necessary.

UDOT Regions, responsible for carrying out road construction and permitting utility projects, also work with the Super Load Team to make sure loads are routed properly around projects. Contractors doing the work do their best to accommodate big loads by moving traffic control or opening lanes.

While simple permits take only minutes, a super big load permit may take up to 48 hours. Since the safety of the public and protection of structures is at stake, MCD Agents are very careful when routing the super loads, says Anderson. “We want to take our time to make sure things are done right the first time.”

Many carriers are familiar with the best routes and applicants can define the best way to get from point A to point B. For example, massive truck beds used in mining operations are detached from trucks and moved through the Salt Lake Valley many times each year to be repaired.

Often, carriers are very familiar with the cities and towns and are sensitive to the needs of the residents. Anderson tells about how a super load move was planned to avoid Raspberry Days in the Bear Lake area. The load was so massive, signals had to be removed and replaced as the big load moved along the route.

The move took place during early morning hours “before everybody lined up to get the raspberry pancakes,” says Anderson. “We had it taken care of pretty quick.”

Many carriers are familiar with the best routes since they move loads often. For example, massive truck beds used in mining operations are detached from trucks and moved through the Salt Lake Valley many times each year to be repaired.
