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:

  • 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:

  • 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.

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.
