The Point Project Now Complete

vms

The barrels are gone, all lanes are open, and The Point project on I-15 is now officially complete.

This two-year, $215 million project widened I-15 to six lanes in each direction between 12300 South in Draper and S.R. 92 in Lehi, a distance of approximately seven miles. The project also replaced the existing pavement with new 40-year concrete, reconstructed the 14600 South interchange as a single-point urban interchange to improve traffic flow, and installed new traffic management technology such as cameras, ramp meters, electronic message signs, and fiber optics.

This section of I-15 is the principal transportation link between Salt Lake and Utah counties. More than 160,000 cars travel through this area each day, including nearly 37,000 trucks. Maintaining I-15 in top condition, and expanding the freeway to meet Utah’s transportation needs, will help Utah’s economy continue to grow.

“Keeping traffic moving on this critical economic lifeline running through the heart of our state was a huge undertaking, and our crews stepped up to the challenge,” UDOT Project Director Tim Rose said.

With the completion of The Point project, nearly all of I-15 along the Wasatch Front has been reconstructed within the past two decades. One last section – in Lehi, from S.R. 92 to Main Street – remains, and is programmed to begin construction in 2020.

Improvements in Layton resume with traffic shift, bridge demolition

LAYTON — With Layton Improved construction resuming after a brief winter hiatus, the Utah Department of Transportation (UDOT) is advising motorists to be aware of traffic pattern changes in Layton around I-15 and the Hill Field Road interchange beginning Wednesday, Feb. 17, 2016.

The Hill Field Road project will move forward with the demolition of existing interchange bridges and construction of a new single-point urban interchange (SPUI). Workers will also finalize improvements to Hill Field Road.  Crews will be working 24 hours a day, six days a week, to finish the project as quickly, efficiently, and as safely as possible while maintaining traffic movement through the area. All traffic lanes will remain open on I-15, and speed limits will not be reduced through the construction zone. Please stay alert and use caution as you drive through the area.

Traffic Shift

Beginning Wednesday, construction crews will shift I-15 traffic in the area onto a detour bridge on the west side of the interstate. Southbound traffic will shift onto the detour bridge on Wednesday morning, Feb. 17. Northbound traffic will make the shift on Thursday morning, Feb. 18. The traffic shift will be in place in both directions through mid-April.

Left turns on the off-ramps will be closed from now through July 2016, so motorists will need to follow the detour signs to turn right and travel through the ThrU Turns.

HillBridge_NoLefts_V2

Trucking companies that normally use Hill Field Road to access businesses west of Layton should plan to use the Layton Parkway Interchange (Exit 330) or Antelope Drive (Exit 332) to access those businesses and industries through July.

Bridge Demolition

Following the traffic shift, the section of Hill Field Road underneath I-15 will be closed on the evenings of Feb 20-21 so crews can demolish both bridges. It is suggested that motorists pay particular attention to  signage that day for detour routes. The new SPUI bridges are being constructed offsite and will be moved into place through UDOT’s innovative accelerated bridge construction process. The northbound part of the bridge will slide into place in early March, and traffic will switch onto the northbound bridge in mid-April. Crews will then complete the southbound bridge and will slide it into place in April.

What to expect when it’s completed

Once the project is completed in Fall 2016, congestion in the area will be reduced by five minutes, thanks to:

  • Four ThrU Turn intersections (already completed)
  • Three additional lanes on Hill Field Road
  • Wider bridges on I-15 over Hill Field Road
  • A single-point urban interchange (SPUI) that will merge traffic at the off-ramps, controlled by one traffic signal.

Since the completion of the ThrU Turns, traffic flow has improved and delays reduced in the area. UDOT and Layton City are working together to tailor solutions that meet the city’s unique traffic challenges, and we’re excited to see the full project benefits realized when all the improvements are completed in fall 2016.

Moving to an intelligent design environment

UDOT’s intelligent design effort includes moving to an all 3D work flow – a revolutionary change in the way state departments of transportation do business.

UDOT is leading the nation in important innovations which will save time, reduce mistakes, and conserve public funding.

3-D models allow every aspect of a road construction project to be viewed from any angle. State DOTs produce 3D design models that are then converted to 2D paper plan-sets to be advertised and delivered to the construction contractor. Plan sets are stacks of paper diagrams that illustrate each aspect of the project, such as pavement layers, drainage structures like pipes and culverts, underground geotechnical features, etc. The plan set production process is 60 to 70 percent of a UDOT designer’s time during pre-construction.

Often, contractors need to re-create a 3D model to build the project. By providing the contractor with a 3D model instead, UDOT will save an estimated 60,000 hours a year, the contractor won’t need to re-create the 3D model, and bid prices will likely be lower.

Other advantages of an all 3D workflow include

  • A more accurate view of project features
  • A more efficient use of technology during construction
  • Better communication between designers and contractors
  • Greater accuracy estimating quantities of materials for building the roadway
  • Elimination and mitigation of errors during design and construction
  • A higher-quality construction product

Automated Machine Guidance on I-80 shows important benefits

Automated Machine Guidance (AMG) allows contractors to use 3D models to program heavy equipment, like excavators and pavers, to work automatically. Most contractors use AMG.

UDOT recently realized some important benefits by providing the 3D model to the contractor on the I-80 Silver Creek to Wanship paving project. Coring tests after paving showed two deficient pavement cores versus eight deficient cores compared to non-AMG pavement. AMG also resulted in fewer ‘must-grind’ corrections. These advantages add up to longer pavement life.

In 2016, Region Two will advertise the I-215 resurfacing project using the 3D model for information only. Providing this model will save the contractor from having to create a 3D model from scratch, may allow for better bid pricing, provide the construction crews with the ability to check final grade with a GPS unit, and help locate underground utilities.

Future vision

Eventually, UDOT would like the contractor to return post-construction 3D ‘as-built’ files which show how the project was ultimately built. With 3D files in hand, UDOT designers will have a much easier task when future work is necessary.

Vote Early, Vote Often for Brigham City DDI in Transportation Awards Competition

BRIGHAM CITY — UDOT’s 1100 South/U.S. 91 DDI project in Brigham City has been selected as a Top 10 finalist in America’s Transportation Awards, sponsored by the American Association of State Highway and Transportation Officials (AASHTO).

The northern Utah project is competing against projects from eight other states to win first place in the competition, which includes a cash prize that will be donated to a deserving charity in Utah.

“This Top 10 project is one more example of why UDOT has a reputation for being a national leader in quality and innovation,” said UDOT Executive Director Carlos Braceras. “I extend my congratulations to everyone who is associated with the project.”

Braceras suggested that anyone who would like to support the Brigham City project in the competition for best transportation project in the United States can participate in the voting for America’s Transportation Awards. “You can vote as many as 10 times per day per email address,” Braceras said.

Voting is currently underway online for the People’s Choice Award in the America’s Transportation Awards competition. To vote, go to http://nominate.americastransportationawards.org/Voting.aspx.

Voting will continue through Sept. 11.

The UDOT project is among 10 finalists in the competition. It is competing against projects from Florida, Kentucky, Indiana, Texas, North Dakota, New Mexico, South Carolina and Montana.

The Brigham City project qualifies in two top categories. One is the National Grand Prize, honoring the nation’s top transportation project as determined by a panel of industry experts and professionals. The other is the People’s Choice Award, which is voted on by the public through online balloting. The winner in each category receives a $10,000 donation to a charity or scholarship fund.

In order to be selected as a Top 10 project, it first had to be selected as a regional winner. The project won in the “Under Budget” category for an innovative design that could have cost as much as $100 million, but through out-of-the-box engineering and sensitivity to geological issues around the area, cost only $14 million.

With more than 20,000 vehicles a day — many of them trucks — originating throughout the region, this old, inefficient interchange was reducing the flow of the economic lifeblood of local communities to a trickle.

The 40-year-old interchange would frequently clog when vehicles at its ramps tried to enter the traffic flow.  The predominant west to south-bound traffic on US-91 was so steady during the day that it was nearly hopeless for other movements to occur.  This prompted risk-taking by trapped motorists at the ramps, and frequent crashes when they did.  Regional special events, like local university football games, would bring traffic to a complete halt.

UDOT traffic planners needed a solution, but the answer was elusive.  Soils adjacent to the Great Salt Lake were saturated by surface groundwater, making the interchange increasingly unstable.  Engineers wondered how to upgrade it without a massive redesign to accommodate the increasing pounding from trucks.  Similar rebuilds had cost upwards of $100 million – prohibitive under state budgets.

The answer: innovate.  Engineers used an innovation to solve the water issue — geofoam — which allowed the new interchange to “float” on soggy soils.  Another innovation — advanced bridge construction — replaced the interchange’s old bridge over I-15 while adding a completely new span in a little more than 10 months.  Finally, the innovative diverging diamond traffic pattern was added to the design to solve the problem of congestion and safety.

The result of all this innovation was an efficient interchange that allows all traffic movements to occur safely and congestion-free, and all for less than $14 million.

New Long-Range Plan released for rural roads

Projects planned over next 25 years will enhance Utah’s economy, quality of life

RICHFIELD —  The Utah Department of Transportation today released its long-range plan forecasting transportation needs in rural Utah over the next 25 years.

The department updates its long-range transportation plan every four years with an eye toward keeping traffic moving now and into the future. The plan focuses primarily on rural areas of the state and identifies a list of projects that will strengthen Utah’s economy and enhance the state’s quality of life.

DSCsr153b

Transportation needs for Utah’s urban areas are developed in cooperation with metropolitan planning organizations like the Wasatch Front Regional Council and the Mountainland Association of Governments. These long-range plans, along with UDOT’s Long-Range Plan, are combined to create Utah’s Unified Transportation Plan, which will be published this fall.

“UDOT follows a fiscally responsible approach to maximize the value of Utah’s infrastructure investment,” said Jeff Harris, UDOT planning director. “The department leverages limited resources in a way that will provide the greatest benefit.”

Harris said the Long-Range Plan considers the unique needs and strengths of rural Utah, including tourism, the energy sector, interstate freight movement, access to recreation opportunities, and the need for enhanced connections between communities. It employs sophisticated travel demand modeling software to anticipate future transportation needs, taking into account projected population growth as well as employment data forecasts.

The plan also reflects the predicted quantity and timing of future funding, as well as public input accumulated during a series of public meetings focused on the draft project list last spring.

Projects listed in this plan include projects to widen roads, add new passing or climbing lanes, modify interchanges and make other needed improvements throughout the state. You can view the Long-Range Plan here http://www.udot.utah.gov/go/lrp.

Mountain View Corridor celebrates partnership with Rocky Mountain Power and Kern River Gas

The Utah Department of Transportation’s Mountain View Corridor (MVC) project celebrated an innovative partnership with Rocky Mountain Power and Kern River Gas on Tuesday, June 16. Representatives from the utility companies, team members from MVC and UDOT management were in attendance. Remarks were given by Joe Kammerer, MVC Project Director; Sharon Seppi; Rocky Mountain Power; Bob Checketts, Kern River Gas; and Shane Marshall, UDOT Deputy Director.

MVC Partnership Meeting 16 June 2015 (5)

UDOT, Kern River and Rocky Mountain Power have been on working on relocating utility lines in preparation for construction to begin on the new roadway from 5400 South to 4100 South in West Valley City, in the Spring of 2016. This included installing 5 miles of 36” diameter natural gas pipelines, 52 transmission line poles (345kv and 138kv).

Since the project began, there were few that imagined such extensive utility work could be completed and coordinated so seamlessly. However, this partnering celebration took place because of the excellent cooperation of all parties involved.

“This is a model for how transportation agencies like UDOT and utility companies can work together,” said Checketts, Vice President of Operations at Kern River Gas. He further explained that this partnership has now set the precedent for how Kern River is working with the Nevada Department of Transportation (NDOT) on another project.

A pin was created in commemoration and was given to all participants symbolizing the partnership between Rocky Mountain Power and Kern River Gas with UDOT.

UDOT projects honored at WASHTO meeting

State projects win in “Quality of Life”, “Under Budget” categories

BOISE, Idaho — Dedication and understanding of the impact state-controlled roads have on motorists in Utah was recognized today, as UDOT projects in Southern Utah and Northern Utah garnered two regional awards in the 2015 America’s Transportation Awards competition.

The announcement today was made at the 2015 Western Association of State Highway and Transportation Officials (WASHTO) annual meeting. UDOT projects were among eight that won in each of the competition’s three categories: Best Use of Innovation, Under Budget, and Quality of Life/Community Development.

UDOT’s Bluff Street at Southern Hills Parkway Interchange was recognized in the Quality of Life/Community Development category, which recognizes “a transportation project that has contributed to the general quality of life and economic development of local communities. These innovative projects better connect people to businesses, jobs, health care facilities, and recreational activities while encouraging a mix of transportation modes. ” With comfortable weather and access to many outdoor activities and destinations, the largest city in Region Four provides so much of what St. George and Washington County residents who value quality of life are looking for.

So many new residents have come to the area seeking this quality of life that existing transportation infrastructure has been over-taxed. Nearly 43,000 cars travel along Bluff Street (SR-18) each day, and another 13,700 go through Red Hills Parkway. The clash of rural vs. urban can best be seen here, where a state highway suddenly becomes a city road where many cyclists and runners converge to get to and around the natural preserve. It’s the meeting point four multi-use trail systems, and is included in the course of many major sporting events in the area. All of this activity in a traditionally constructed intersection places residents and visitors at risk.

This was how the intersection looked before the project

This was how the intersection looked before the project

In order to accommodate the current population as well as the expected growth through 2030, UDOT, the City of St. George and the Southern Utah Bike Alliance (SUBA) collaborated to reconfigure the intersection by creating a center exit interchange.

The center exit interchange creates a safer section of road, while also maintaining a steady flow of traffic. Highway travelers can continue on their way on the outside lanes, while those needing local access take the inside lanes to an intersection that allows east-west travel.

The construction team saved $4 million in construction costs by utilizing the natural topography of the area and building the project within natural grades.

The project also integrated bike/pedestrian paths into the design, with box culverts under SR-18 allowing for safer multimodal transportation under busy roadways, thus connecting the community in a safe, efficient and positive way.

“UDOT should be commended for their positive design process that encourages outside voices and ideas,” said Craig Shanklin, SUBA President. “This was a great example of how the community can be involved in the design process and lead to a better outcome for all users.”

The Diverging Diamond Interchange at Brigham City’s US-91/1100 South location was honored in the “Under Budget” category. That category honors “a project demonstrating transportation efficiency while promoting economic and fiscal responsibility. The award recognizes a successful project brought in under budget that provided the greatest cost savings to the state(s) while offering maximum performance.”

How do you move a steadily increasing traffic flow through an aging, small interchange at the connection of US-91 and Interstate 15, near the northern Utah city of Brigham City?  With more than 20,000 vehicles a day — many of them trucks — originating throughout the region, this old, inefficient interchange was reducing the economic lifeblood of local communities to a trickle.

The result? An efficient interchange that allows all traffic movements to occur safely and congestion-free, and all for less than $14 million.

“What UDOT and the project team eventually chose to do was not only innovative, but a brilliant solution to an extremely difficult situation with many built-in constrictions,” said Bradley Humpherys, a Senior Transportation Project Manager for Stanley Consultants.

Utah’s two projects — along with projects in California, Colorado, Montana, New Mexico, North Dakota, and Texas — will compete against projects from other regions in the U.S. for a National Grand Prize, the People’s Choice Award and $10,000 prizes to be given by the winners to a transportation-related charity or scholarship program.

The top two national winners will be announced in September at the AASHTO Annual Meeting in Chicago.

“These projects are a small sampling of the many ways in which state DOTs are improving peoples’ quality of life and providing for a vibrant economy,” said John Cox, American Association of State Highway and Transportation Officials President and Director of the Wyoming Department of Transportation.

The America’s Transportation Awards – co-sponsored by AASHTO, AAA and the US Chamber of Commerce – annually recognizes the best of America’s transportation projects in four regional competitions.  Learn more about the projects and the competition at: AmericasTransportationAwards.org

State Transportation Commission tours UDOT projects in Summit County

PARK CITY — On Thursday, June 25,  the State Transportation Commission toured several areas in Summit County to see current and recent roadway improvement projects in the county.

The Utah Department of Transportation (UDOT) has been working with Summit County, Park City, and Snyderville Basin Parks, Trails and Recreation on improving transportation routes in the area.

“Summit County is a popular destination for recreation enthusiasts year-round,”  says UDOT Region Two Director Nathan Lee.  “Keeping the flow of motorists, cyclists, and wildlife moving through the county efficiently and safely is a top priority for us.”

The commission takes a tour of the recreation/wildlife underpass at US-40 in the Snyderville Basin.

The commission takes a tour of the recreation/wildlife underpass at US-40 in the Snyderville Basin.

In the past five years, UDOT has invested $102 million in roadway improvements in Summit County.  Some of those projects include:

-I-80 from Kimball Junction to SR 224 Study

This study looked at different scenarios to expand the capacity of SR 224 near Kimball Junction to accommodate future traffic and improve mobility.  Three recommendations were made, including a 7-lane section on SR 224, a continuous flow intersection at Olympic Parkway/Newpark Blvd., and a third left turn lane from northbound SR 224 to westbound I-80.  A final recommendation has not been chosen and funding for construction has not been secured.

-Wildlife Underpass Crossing at US 40

Completed in November 2014, this new underpass crossing provides recreational access and connectivity west of US 40 with the Frontage Road east of US 40.  The underpass also enhances safety for drivers and trail users, while at the same time reducing auto-wildlife crashes.

-SR 224 between Richardson Flat and Round Valley Drive

UDOT repaved and widened S.R. 248 to five lanes (two general purpose lanes in each direction with a two-way left turn lane) from Richardson Flat Road to Round Valley Drive. The project also included the installation of bike lanes from Wyatt Earp Way to Richardson Flat Road and intersection improvements at Richardson Flat Road and S.R. 248.  This project was completed in 2013.

The Commission stopped at S.R. 248, east of Comstock Drive to view a pedestrian tunnel near Treasure Mountain Middle School in Park City.

-SR 224 between Bear Hollow and I-80

UDOT completed a three-inch repaving on S.R. 224 from Bear Hollow to the I-80 interchange in July 2014.  The project also included new radar signal detection, pedestrian ramp upgrades and a shared shoulder for Park City Transit buses/ bikes on the east side.

Current projects under construction include the following:

-I-80 between Silver Creek and Wanship

This $43 million project replaces asphalt, upgrades drainage systems, and installs overhead variable message signs (VMS) to better communicate road conditions on Interstate 80 between Silver Creek and Wanship.  Construction began in December 2014 and is scheduled for completion in late 2015.

-Judd & Hobson Lane Bridges at I-80

This $2.7 million renovation project prolongs the life of the both the Judd and Hobson Lane bridges along Interstate 80 between Coalville and Hoytsville.  Originally built in 1967, the bridges provide connectivity and enhance safety for drivers.  Renovations began in June 2015 and are scheduled for completion in the fall of 2015.

Upcoming projects in Summit County include the following:

-New westbound truck lane on Interstate 80 between Parley’s Summit and Jeremy Ranch

To improve mobility and enhance safety on Interstate 80, UDOT is designing a passing truck lane between Parley’s Summit and Jeremy Ranch.  The $17 million design project will begin in 2017.

-US 40 bridges near Jordanelle Reservoir

This $4.2 million project will preserve seven bridges near the Jordanelle Reservoir, which are frequently used by motorists visiting the area for recreation.  The bridges were originally built over 20 years ago. Bridge preservation work begins in 2016.

Use Click ‘N Fix to help Utah water quality

We’re interested in hearing from you on UDOT Click ‘n Fix — but not just about potholes and traffic signals. We also want your help stopping water pollution. That’s right, water pollution. I was surprised when I first heard about this too! Besides having miles and miles of highways to monitor, we also have acres and acres of right-of-way, and we want to make sure any bodies of water downstream, or near these areas, remain clean and pollutant-free.

Here’s where you come in: If you see any spills or illicit discharges on a UDOT maintained route, open the Click ‘n Fix app, answer a few questions and we’ll have our risk management division investigate.

Big Cottonwood Creek flows right next to S.R. 190 and the UDOT right-of-way. Please let us know if you see any spills or pollutants making their way into our waterways by using UDOT Click ‘n Fix. Not only in obvious places like Big Cottonwood Canyon, but also in populated areas where storm drains eventually empty into water as well.

Big Cottonwood Creek flows right next to S.R. 190 and the UDOT right-of-way. Please let us know if you see any spills or pollutants making their way into our waterways by using UDOT Click ‘n Fix. Not only in obvious places like Big Cottonwood Canyon, but also in populated areas where storm drains eventually empty into water.

So, what are spills and illicit discharges?

Spills are when something other than storm water unintentionally “spills” on the highway or right-of-way. For example, after a car crash, a vehicle may leak oil or antifreeze onto the highway. It needs to be properly cleaned up and disposed of to keep the pollutants out of the storm drain or an adjacent stream, river, lake or wetland.

Illicit discharges may also be unintentional or they may be illegal dumping activities. Some examples of illicit discharges are sprinkler runoff that contains pesticides, fertilizers or weed killers; detergents, oil and grease from washing a car; or someone dumping waste into a storm drain. We also want to know if someone is connecting a pipe or ditch to UDOT’s property or drainage system.

The UDOT Click ‘n Fix app is available on Google Play or iTunes and on our website. Please keep in mind that if you witness something that is endangering public safety, please call 911. This not only applies to spills and pollutant discharges, but also our other Click ‘n Fix issues like road debris.

With your help, we hope to keep pollutants from entering storm drains and making it into Utah’s streams, rivers, lakes and wetlands. Utah is such a beautiful state, and water is so precious that you can count us in for doing everything we can to keep it pristine.

 

Layton ThrU Turn, SPUI, set to relieve congestion

LAYTON — The Utah Department of Transportation and Layton City are working together to tailor solutions to meet the city’s unique traffic challenges.

One of the main challenges is near Hill Field Road and the interchange with Interstate 15. Typically, it takes motorists about 10 minutes to go a half-mile from Main Street to the Layton Hills Mall, with cars frequently backing up all the way to the freeway. UDOT and the city are ready to construct solutions in this area in two phases, aimed at improving traffic flow, driver safety, and access to local businesses.

Phase One will have new ThrU Turn intersections built on Hill Field Road at Main Street and at Gordon Avenue (near the Layton Hills Mall). A ThrU Turn intersection improves traffic flow by eliminating left turns at the main intersection. Drivers wishing to turn left continue straight to the intersection, then make a U-turn at a specially designed turnaround. Construction will start on Sunday, June 14, and is schedules for completion in 90 days — in time for Black Friday and other holiday shopping.

Phase Two will construct a Single Point Urban Interchange at the Hill Field Road interchange on I-15. On these interchanges, all traffic from the off- and on-ramps (as well as Hill Field Road) is controlled by a single traffic signal. This design imporves the flow of traffic and enhances safety for drivers. The interchange will be completed during the 2016 construction season.

According to computer data, driving along Hill Field Road will take half as long when construction is complete. In 25 years, that drive time will be 1/4 as long as if the intersection stayed as-is.

The majority of lane closures are scheduled at night, as part of UDOT’s efforts to work as effectively as possible to minimize delays during construction. When complete, drivers will save an average of 5 minutes off their commute.

Residents with questions can meet the contractor on Tuesday, June 16 from 5-7 p.m. at the Layton Hills Mall. Current information will also be posted at the Layton Improved website, and you can call the project hotline at 801.904.9064.
