I-80 Crash Silver Barrel Awards

Executive Director Carlos Braceras awarded twelve Region Two employees with a Silver Barrel Award for their efforts related to a semi crash on I-80 that closed the road for several hours. Details of their efforts are below and the recipients included:

  • Shane Bushell
  • Rick Debban
  • Nick Jarrett
  • Robert Miles
  • Cody Moore
  • Stuart Ovard
  • Rick Potter
  • Bryant Richins
  • Jason Richins
  • Layne Thornton
  • Dottie Weese
  • Ron Williams

On July 16, 2014, Summit County Dispatch called Bryant Richins the Echo Station Supervisor around 5 a.m. and asked him to respond to a semi crash on I-80 westbound in Echo Canyon.

Due to the severity of this crash and with both semis on fire, I-80 was closed in both directions.

Bryant and his crew provided the traffic control and set up a left lane closure from the Echo Port of entry to the maintenance turnaround at milepost 183. This provided emergency vehicles a way to travel westbound if they needed to get past the crash scene.

I-80 eastbound was opened to one lane of traffic around 8 a.m. The crew was then asked for material to contain the water and hazardous runoff from fighting the fire. Two trucks from the Wanship Station hauled material up and contained the runoff.

The crew then started to assist in the clean up of the crash but the fireman in charge was concerned with the possibility of the loads flaring up. They discussed several possibilities and it was decided the UDOT crew would tip the loads over with their loader so they could get water on it to better extinguish the smoldering fire. This alone was estimated to save a couple of hours in the clean up of the accident.

The UDOT Echo Crew then worked with the tow company and firemen and offered to use their four UDOT ten wheel dump trucks and loader to haul the debris to the landfill. The Summit County Fire Department tried to cut up the burnt semis with their chop saws but it was taking too much time. Bryant offered to have his equipment operator go in with the loader and smash and roll up the debris and then load it in to UDOT’s ten wheelers. This saved an estimated four hours. Bryant then proposed his plan with the UDOT Area Supervisor and called Morgan Asphalt around 9 a.m. to notify them he would need their services in Echo Canyon to rotomill and repave the damaged/burnt asphalt. The crash debris was cleaned up and Morgan Asphalt was able to start rotomilling and paving around 2 p.m. The interstate was repaved and all lanes open to traffic by 5:45 p.m.

This is a great example of successful partnering with Utah Highway Patrol, Summit County Law Enforcement, Summit County Fire Department, Summit County Health Department, Moores Towing, the UDOT Incident Management Team, the UDOT Region Safety Manager, the UDOT Area Supervisor, UDOT Wanship Station 236, and UDOT Echo Station 238! Due to this successful partnering they were able to safely reopen Interstate I-80 and estimated 6 hours early.

Dan Betts Silver Barrel

Dan Betts received a Silver Barrel Award for his solution to striping problems on I-80 in Parley’s Canyon. After receiving several complaints about low striping visibility Dan and UDOT Central Maintenance determined there was a problem. Dan contacted the manufacturer because the striping was still under warranty and came up with a great solution.

  • The manufacturer would replace the striping tape on I-80 between Mt. Aires Exit 132 and Lambs Canyon Exit 137, including installation and traffic control.
  • The upper section of I-80 from Lambs Canyon Exit 137 to Kimball Junction Exit 145 paint would be applied over the existing striping tape since the pavement is in need of treatment and tape would not be cost effective. The manufacturer would install the paint including the traffic control.
  • UDOT Region Two would provide the grooves for the striping tape to be applied.
  • The manufacturer would provide an additional four year warranty for the entire section, both taped and painted.

Through Dan’s efforts and negotiating skills he was able to improve striping on I-80 through Parley’s Canyon.

Urban speed limits raised to Keep Utah Moving

SALT LAKE CITY — Utah Department of Transportation crews canvassed the urban interstate across the Wasatch Front, replacing speed limit signs while officially changing the speed limit from 65 to 70 mph.

A new 70 mph speed limit sign waits to be installed.

A new 70 mph speed limit sign waits to be installed.

In an effort to optimize mobility and Keep Utah Moving, crews from UDOT Regions One, Two and Three spent all day on December 8th, changing out 99 signs from Spanish Fork to Ogden. In many instances, the crews simply placed a decal on the existing sign, but several of the older signs were replaced outright.

The speed limit increased on Interstates 15, 80 and 215. However, two sections of I-80 will remain at 65 mph, as engineering studies show the terrain doesn’t allow for a speed increase.

The choice to implement the new speed limits was based on several studies, and in response to last year’s legislation (H.B. 80).

Utah is not the first state to raise speed limits to 70 mph or faster. Nearly one-third of the United States has speed limits set at 70 mph or faster in urban areas, and more than two-thirds of states have increased them in rural areas.

Automated Queue Warning Detection System in the Work Zone

Prepare to Stop VMSThis summer, Region Two began work on Redwood Road from I-80 to North Temple to rotomill and resurface the roadway with a thin bonded PCCP 6” overlay. One of the biggest challenges on the job was maintaining traffic through the work zone while also maintaining side-street and business access. This issue was complicated by the high number of large trucks in the area. These trucks not only utilize a significant amount of available queue space on the ramps, they also take more time to climb the incline at the interchange before clearing the signal. These factors required significant coordination to keep traffic moving.

Our contractor, Dry Creek Structures, and construction crew worked closely with the Traffic Signal Maintenance group to split phase signals and move detection zones to accommodate traffic through the work zone. We also worked closely with Grant Farnsworth at the TOC Traffic Signals Desk to adjust signal timing as the work zone configuration changed.

From a traffic safety perspective, our top priority was to minimize queuing on the
westbound I-80 ramp and prevent stopped traffic on mainline I-80. Despite the team’s best efforts, traffic was occasionally still backing onto mainline I-80 while waiting to exit at Redwood Road. To help address this queuing problem, working with Marge Rasmussen in Region Two Traffic and Safety, and Project Manager Peter
Tang, an Automated Queue Warning Detection System was change ordered into
the project and installed on the I-80 westbound off-ramp to Redwood Road.
With this system, the occupancy rate was monitored near the gore point of the off-ramp. When the system detected stopped cars at this location, a warning message was activated at a Variable Message Sign (VMS) upstream of the off-ramp alerting motorists of “STOPPED TRAFFIC AHEAD” and “PREPARE TO STOP.”

How it works: A sub-contracted vendor (Ver-Mac) installed a radar sensor, cellular
modem and solar panel on a highway lighting pole near the bottom of the off
ramp. They also placed a VMS equipped with a cellular modem upstream of the off
ramp. When the vendor’s software system (Jam-Logic) detected an occupancy rate greater than 10 percent at this location, a message was activated at the VMS alerting travelers to the stopped condition ahead. Once the queued traffic had dissipated, the VMS message was automatically turned off and remained off until ramp queuing was detected again.

In addition to the VMS message activating when a queue was detected, email messages were also sent to the TOC Operators, the Signal Timing Engineer and the Resident Engineer, alerting them to the situation. When possible, adjustments were made to the signal timing to help clear the ramp traffic.

Results: The project team is not aware of any accidents at this location after the automated queue warning system was installed. Typically, the system was activated 10 times each day throughout the week or an average of 13.4 times on weekdays. Even during low traffic volumes, just a few long trucks on the ramp can back up traffic and activate the system. While the system was live, the queue warning messages were displayed 256 times for a total of 2,327 minutes. The average display time was 9 minutes. The maximum display time was 56 minutes (on August 23 starting at 9:19 a.m.).

Logical Automation Rules Chart“Doing advanced queue warning is a great operational benefit, but what the TOC appreciated most was the communication between the project and the control room. When the control room knows what’s going on, we’ll help out in any way that we can. In this case, we monitored the queue system and helped ensure that it was functioning as advertised – which it was,” explained Glenn Blackwelder, Traffic Operations Engineer.

Future Applications: The automated queue warning detection system was a valuable addition to our “tool box” for managing traffic issues in the construction work zone on the Redwood Road project. In the future, perhaps other projects could benefit from this or other types of technology to help address traffic control issues within construction work zones.

I-80 Silver Creek Reconstruction

Photo of concrete pavingDrivers traveling through Summit County on I-80 have become familiar with one of the Region’s largest construction projects: the concrete reconstruction of I-80 from the U.S. 40 junction (MP 148) to Wanship (MP 155). Work began in June and is scheduled to continue through November of 2015 (construction will be halted during the winter months between 2014 and 2015).

The project includes replacing the freeway’s asphalt with new concrete pavement. In many locations, the existing asphalt will be removed and the pavement will be completely reconstructed. The new concrete will help accommodate the heavy trucks that travel in both directions along this key freight corridor and will prolong the life of the roadway.

UDOT’s contractor, Geneva Rock, is constructing the road in two principal phases. Phase one – the current phase – has shifted all traffic to the westbound lanes, allowing crews to reconstruct the eastbound lanes. In November, once the eastbound lanes are complete, lane restrictions will be lifted and traffic will be returned to its normal configuration. In the spring, crews will shift all traffic into the newly reconstructed eastbound lanes and complete work in the westbound lanes.

Photo of concrete pavingAs part of the concrete reconstruction, a unique pavement base material is being used to provide strength and stability to the pavement. The material, called Cement-Treated Asphalt Base (CTAB), provides a strong and stable base for the concrete to ensure durability and longevity. The CTAB material is formed by pulverizing the existing asphalt and adding cement powder and water to make a low strength concrete.

Typically, concrete pavement is either overlaid over the existing asphalt (as with the concrete paving project on S.R. 201), or a thin layer of asphalt is applied to the existing pavement and then the concrete is overlaid. On this section of I-80, however, the existing pavement is deteriorating too quickly to provide a suitable base. Instead of overlaying an additional layer of asphalt, CTAB was selected because of its lower cost and better resistance to water damage. While concrete treated bases have been used for a long time, this is the first instance in Utah where a cement treated base uses 100 percent recycled asphalt.

The project team has been involved in an extensive stakeholder outreach and public information program. Key stakeholders, such as Summit County, local emergency services, and the communities of Tollgate and Promontory, have been kept informed and consulted throughout the project to minimize impacts wherever possible and coordinate essential information such as emergency plans.

Photo of concrete pavingUDOT and Geneva Rock have worked together to address stakeholder concerns and mitigate risks associated with this traffic configuration. Local emergency crews are allowed to access the work zone in the event that they are not able to travel through open traffic lanes in a timely manner. Tow trucks are on-call at both ends of the construction zone to reduce response times to incidents and keep traffic moving.

Due to the long-term closure of Tollgate’s eastbound on- and off-ramps, accommodations needed to be made to provide residents access to their community, especially in case of emergency. The project team worked with the neighboring Promontory development to allow Tollgate residents to use of Promontory’s private access roads in order to bypass I-80 as they travel to and from Park City.

UDOT, Geneva Rock, and the local stakeholders have established a good working relationship for this significant reconstruction – a project that will ensure this section of I-80 stays in good repair for years to come.

I-80 Parley’s Canyon Drainage Improvement Project Wins Excellence in Concrete Award

Last summer’s Drainage Improvements project on Interstate 80 in Parleys Canyon was recently recognized with the Excellence in Concrete Award from the Intermountain Chapter of the American Concrete Institute. The award recognized the team of UDOT, H.W. Lochner, W.W. Clyde and its subcontractors, and Geneva Pipe and Precast for designing, casting, and installing the new culvert adjacent to I-80. This drainage project, which was completed in fall 2013, installed more than 10,500 feet of 66-inch reinforced concrete pipe along a two-mile segment of I-80 near the mouth of Parleys Canyon. Crews also installed 6,700 linear feet of median and lateral drains, along with 80 concrete box structures. The new drainage system, with a 100-year design life, replaces the original corrugated metal pipe that was installed prior to construction of I-80 in the 1960s.

As many of the pipe sections are fabricated with slight differences to accommodate elevation changes or curves in the two mile-long culvert, each section had to be placed in exactly the right spot. The pipe included beveled segments, where the spigot end of the pipe had a slight bevel to the left or right, as well as straight segments. These segments allowed the pipe to bend gradually to match the grade and curves of the roadway. To install each segment, an on-site surveyor took measurements to ensure both vertical and horizontal alignment.

Significant challenges faced by the project team included maintenance of traffic – 45,000 cars each day traveled through the work zone – and the solid rock of the canyon, which required blasting in several locations merely feet away from the edge of pavement. In total, 10 separate blasts were carried out, for a total of more than 2,200 linear feet. The project was completed under the $11.8M budget just in time to suit the unique weather and stream flow conditions in the canyon.

According to the ACI Intermountain Chapter, the ACI Excellence in Concrete Awards “recognizes the innovative and aesthetic uses of concrete by owners, architects, engineers, contractors and ready mix producers.” This award is the latest recognition of the combined efforts of UDOT and the contractor team to meet challenges and complete a quality project that will benefit Utahans for years to come.

2014 Top 10 Construction Projects

The Utah Department of Transportation’s 2014 construction season will start soon. With more than 175 projects worth more than $800 million, UDOT is in for a busy summer.

A few large-scale expansion projects will help optimize mobility by adding new lanes and roads to accommodate Utah’s growing population. In addition, many preventive maintenance projects will help preserve the state’s infrastructure – keeping roads and bridges in good condition, and avoiding the need for more costly repairs in the future. The department will also continue to use innovative technology to improve traffic flow with the installation of the sixth and seventh diverging diamond interchanges in the state.

The following is a list of the top 10 projects statewide in 2014:

  1. I-15, South Davis County 
    UDOT will extend the longest continuous Express Lanes in the country with the reconstruction of I-15 in Davis County this summer. This project also includes the replacement of multiple bridges from North Salt Lake to Farmington in addition to new interchange configurations at 2600 South and 500 South, which will help improve traffic in those areas. A new pedestrian bridge at Parrish Lane and sidewalk improvements on 500 North and 500 South are also included in the project. Construction is scheduled to start in mid-April and is expected to be complete in 2015. Budget: $117 million
  2. S.R. 201 Reconstruction, Salt Lake County

Budget: $42 million
  4. I-15, South Cedar City DDI, Cedar City 
    Crews will reconfigure the I-15 interchange at Exit 57, on the south end of Cedar City, as a Diverging Diamond Interchange (DDI) to improve the flow of traffic for cars, bikes and pedestrians. It includes new ramp construction and modifications to Main Street and the frontage roads. This will be the sixth DDI in Utah. The project is underway and is expected to be complete in fall 2014. Budget: $10 million
  5. Riverdale Road Reconstruction, Roy
    UDOT is reconstructing Riverdale Road between the I-84 interchange and S.R. 126 in Roy to improve traffic flow and reduce delays in the area. The project will replace the existing asphalt with new concrete pavement, add a northbound off-ramp and a southbound on-ramp at I-15, and construct two new intersections as well as a new bridge over the freeway. Construction is underway and is scheduled for completion in late fall 2014. Budget: $24 million
  6. I-15, 1100 South DDI, Brigham City 
    UDOT is converting the existing 1100 South interchange on Interstate 15 in Brigham City to a DDI – the seventh in the state, and the first in northern Utah. This innovative interchange will improve the flow of traffic for drivers traveling to and from Logan on U.S. 91. The north half of the interchange is under construction and will be completed in summer 2014. Once the north half is complete, traffic will be switched to the new bridge, crews will demolish the existing bridge, and the south half of the interchange in scheduled to be constructed by fall 2014. Budget: $$10 million
  7. I-80, Parleys Resurfacing, Parleys Canyon
    UDOT is resurfacing Interstate 80 in Parleys Canyon from the mouth of the canyon (near Foothill Drive) to the Ranch exit (exit 132).This maintenance project will replace several areas of rough pavement throughout the canyon with new durable asphalt.

Variable Speed Limit Signs Now Activated on I-80

Variable Speed Limit sign on I-80 in Parley’s Canyon

The UDOT Traffic Operations Center (TOC) now has a new tool to enhance safety for drivers  on I-80 – one of the most heavily-traveled roads in the state. Last Wednesday (Jan. 8), 15 new variable speed limit (VSL) signs were activated along I-80 in Parley’s Canyon. The new signs will be controlled by the TOC to help maintain consistent traffic flows and assist drivers in adjusting speeds when necessary due to weather conditions.

The 15 signs – 8 eastbound and 7 westbound, located between the mouth of the canyon and Jeremy Ranch, are equipped with LED display screens that allow UDOT to remotely adjust speeds. These adjustments will be made based on driver behavior and road conditions.

“We are always looking for new technologies to help us manage traffic more effectively and enhance safety,” said UDOT Region 2 East District Engineer Robert Miles. “These signs will help keep drivers moving and reduce the number of weather-related crashes in Parley’s Canyon.”

The variable speed limit signs in Parley’s Canyon have been divided into four zones – an eastbound lower zone and westbound lower zone, from the mouth of the canyon to Mountain Dell/Lambs Canyon, and an eastbound upper zone and westbound upper zone, from Mountain Dell/Lambs Canyon to Kimball Junction. When a speed limit is adjusted for a specific zone, the new speed limit will be displayed on all signs within the same zone. These zones were created because of the differences in weather patterns and average speeds observed in the canyon due to changes in elevation.

The TOC will monitor speed limits in the canyon. In the event of poor weather or low visibility, a traffic engineer will be able to review information such as current road conditions, weather forecasts, snowfall rates, observed speeds, and reports from maintenance personnel. Based on this information, the engineer can make the decision to reduce the speed limit as needed. Depending on conditions, speed limits may range from 35 to 65 miles per hour.

The new variable speed limit signs are the first of their kind in Utah. Other states, including Washington, Wyoming, Colorado and Nevada, currently use these signs and have observed a reduction in weather-related crashes in areas where these signs are employed. Washington (Snoqualmie Pass – I-90) and Wyoming (east of Evanston – I-80) in particular are using these signs in areas similar to Parley’s Canyon: interstate highways with moderate to heavy traffic, with significant elevation differences, that are prone to inclement weather.

The Parley’s Canyon VSL project was developed jointly by UDOT and the Utah Highway Patrol (UHP). The speed limits posted on these signs are not merely advisory speeds, but regulatory speed limits that will be enforced by UHP troopers.

I-80 in Parley’s Canyon was selected as the location for this pilot project due to its changing weather conditions, heavy traffic, and existing fiber optic communications network. The investment for the design and construction for the new signs was $750,000, and the annual operating expense is estimated between $7,500 and $10,000. UDOT is also considering installing variable speed limit signs in other locations around the state, such as Sardine Canyon and Provo Canyon, based on the results of this project.

Silver Barrel Awards for Maintenance Station 225

Photo of crew members from maintenance station 2425 receiving their Silver Barrel AwardsExecutive Director Carlos Braceras presented several Silver Barrel Awards to employees from Maintenance Station 225 – Salt Lake Metro. The first award was presented to Station Supervisor Jake Brown for his exemplary service assisting a community group in their neighborhood clean up of the 600 North overpass.

On Saturday, Nov. 9, the Capitol Hill Neighborhood Council and the Rose Park Community Council co-sponsored a clean up of the 600 North overpass. Several community residents and almost thirty West High School JROTC students attended the event. Anticipating that most of the students would not have tools or gloves for the clean up, the Capitol Hill Neighborhood Council asked UDOT for a little help. In response, Jake supplied brooms, shovels, rakes, gloves, vests and garbage bags to the group. The group was thrilled with the support and readily put everything to good use.

Photo of Carlos Braceras presenting maintenance station 2425 with Silver Barrel AwardsJake’s willingness to support his community is a key reason why he is so deserving of the Silver Barrel Award. As Capitol Hill Neighborhood Council Chair Richard Starley wrote, “We could not have done it without Jake’s support. We appreciate his willingness to help and follow through on our requests. . . . The overpass and I-15 interchange haven’t looked this clean since they were built.”

Members of Jake’s crew, Fred Baney, Mike Gailey, Robert Giolas, Brian Goins and Curtis Trott, were also presented a Silver Barrel for assisting the Salt Lake City Fire Department with containment of a semi fire on the northbound I-15 ramp to westbound I-80.

On the morning of December 5, 2013 the maintenance station was contacted at 3:20 a.m. to provide assistance with the fire fighting efforts. Due to the cold temperatures crew members were concerned about ice and responded with a plow truck and sander, a loader and a liquid brine truck with a hose attachment. Salt Lake City fire trucks began to run low on water so Photo of Carlos Braceras congratulating and thanking maintenance station 2425 crew membersUDOT crew members used the brine truck to help douse the flames. The loader was used to expose the burning cargo allowing fire crews put out hot spots.

Once the fire was out Jake and his crew cleaned up the debris, assisted the tow company with removing the semi and its cargo, salted and removed ice patches and had the ramp open for the morning commute. Congratulations to these very deserving individuals.

2013 Construction Season Nears the End

The leaves have turned, the first snow has fallen on the mountains, and the 2013 construction season is nearing an end. UDOT and contractor crews have completed more than 200 road construction projects statewide in 2013. By the end of the year, 216 projects will have been carried out state roads and Interstates from Plymouth to St. George and from Wendover to Vernal. Each one of these projects was designed to help accomplish one or more of UDOT’s strategic goals:

    Photo of crews working along I-80 in Parleys Canyon

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

In 2013, most construction projects fell under the goal to Preserve Infrastructure. These repaving and rehabilitation projects will keep Utah’s roads in good condition and prevent the need for more costly repairs in the future. Maintaining our highways helps them last as long as possible, and benefits the economy by keeping people, goods, and services moving throughout the state.

In 2012, UDOT completed 229 projects with a total value of $2,783,444,049, which included the I-15 CORE and Mountain View Corridor projects. By comparison, the total value of projects scheduled for completion in 2013 is $631,489,082. To make the best use of a much smaller budget during the 2013 construction season, the department focused on maintaining and making minor improvements to Utah’s roads, rather than major expansion or reconstruction efforts.

During the 2013 construction season, UDOT has resurfaced or repaired pavement on more than 400 miles of Utah highways and roads, and has completed 12 bridge repair or replacement projects. Some notable projects that have been completed or are scheduled for completion this year include:

    Workers constructing a new bridge over I-15 as part of the new DDI at St. George Boulevard.

  • I-80 Culvert Installation: Workers installed approximately two miles of 6-foot-diameter concrete pipe along I-80 in Parley’s Canyon to replace the original drainage system constructed in the 1960s.
  • I-15 Widening: Crews widened an 8-mile section of I-15 in southern Utah County from two lanes to three this year to reduce congestion and accommodate future growth in the area.
  • St. George Boulevard Diverging Diamond Interchange (DDI): Workers are converting the existing interchange at I-15 and St. George Boulevard into Utah’s fifth operating DDI to improve the flow of traffic.
  • U.S. 89/91 Repaving: Crews repaved U.S. 89/91 in Cache County from Sardine Summit to Wellsville.
  • U.S. 89 (State Street) Widening: Workers widened and repaved a two-mile section of State Street between Orem and Pleasant Grove.
  • Bangerter Highway Continuous Flow Intersection (CFI): Crews completed a new CFI at the intersection of Bangerter Highway and 13400 South to improve traffic flow in southwest Salt Lake County. Utah leads the nation with 11 CFIs (there are only 20 total in the nation).
  • I-215 Concrete Maintenance: Workers repaired concrete on I-215 from S.R. 201 to North Temple to extend the useful life of the pavement.

Moving forward in 2014, UDOT will widen I-15 at the Point of the Mountain and in Davis County, as well as continue its aggressive focus on maintaining existing roads.
