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 www.udot.utah.gov.
  • UDOT’s Twitter Account — Follow UDOT’s Twitter feed at twitter.com/UtahDOT 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.

Optimize Mobility

The goal of optimizing mobility continues to include the need to build new highways, expand existing highways, build more bicycle and pedestrian paths and expand the transit network. UDOT accomplishes this by adding capacity, managing lanes, developing innovative cross roads, coordinating signals, and providing traffic information.

Since 2006, more than 575 lane miles have been added to the state system from various programs that fund more than 100 projects. Currently, capacity projects are primarily funded through the Transportation Investment Fund (TIF). Some of these projects include the I-15 CORE, Mountain View Corridor, US-40 passing lane improvements, SR-18 intersection upgrades at St. George Blvd. and US-6 passing lane improvements. These capacity projects dramatically improve delay on Utah roadways.


Without capacity improvements, delay along the Wasatch Front would have experienced a three-to-five fold increase.

UDOT currently has 124 miles of Express Lanes (62 miles both northbound and southbound) with 54 continuous miles between Spanish Fork and North Salt Lake City making Utah’s Express Lanes the longest continuous Express Lanes in the country. More than 13,000 Express Pass transponders have been purchased, speeds average 9 mph faster than the general lanes and travelers experience a higher level of safety.

Developing and constructing innovative cross roads is a fundamental in optimizing mobility on Utah roadways. Flex Lanes, Commuter Lanes, ThrU-Turn Intersections (TTI), Diverging Diamond Interchanges (DDI) and Continuous Flow Intersections (CFIs) decrease delay at intersections, reduce travel time, improve safety, and reduce the length and cost of construction.

The Traffic Operations Center (TOC) continues to be the key to providing a cost-effective and and efficient solution to help relieve congestion on Utah’s roads and highways. Using advanced technologies such as cameras and traffic/weather sensors, operators in the TOC can monitor traffic, detect problems and take actions necessary to return traffic flow to normal.

UDOT uses a variety of methods to provide actual travel times and accurate traffic and weather information to help drivers make choices that reduce delay, prevent crashes and improve air quality. By implementing an extensive Intelligent Transportation System (ITS), UDOT is able to know what is happening on Utah roads, and provide travelers the information they need to plan their routes. UDOT communicates travel information online at udot.utah.gov and through variable messages signs (VMS), traffic cameras, twitter, facebook, and YouTube, and the UDOT Traffic App.
