Construction to Ramp Up on Utah’s Roads

UDOT warns drivers to expect delays as crews build new interchanges, widen bridges and repave existing highways

With construction ramping up, today UDOT announced the projects that will affect drivers the most in 2021. Drivers are urged to plan ahead and stay informed to avoid delays.  

UDOT will be working on 185 projects across the state in 2021, with a value of $3.45 billion over the life of the projects, many of which span multiple years. Planned improvements range from repaving rural highways and building freeway-style interchanges to widening and repaving interstates and demolishing and rebuilding bridges. The traffic delays from these projects range from overnight lane restrictions to full road closures with major detours.

“These projects are an essential part of our ongoing efforts to connect our communities and keep our economy strong,” Region Two Director Robert Stewart said. “We’ve planned this work to minimize inconvenience for drivers and residents, but we want everyone to be aware that there will be delays, restrictions, and changes to your daily commute and other travels.”

One major project that drivers should prepare for will reconstruct sections of I-80 and I-215 in eastern Salt Lake County. Crews will also add a new eastbound lane on I-80 and reconstruct three bridges along I-80 at 1300 East, 1700 East, and 2000 East. This will reduce travel delays and improve the condition of this major cross-country interstate. Construction is scheduled to begin later next month. Drivers should expect overnight and weekend lane closures on I-80 and I-215, as well as some complete closures of I-80 during bridge work.

As one of the fastest-growing states in the country, Utah is expected to nearly double its population over the next 45 years, according to the Kem C. Garner Policy Institute. In fact, Utah had the highest growth rate in the country over the past 10 years, according to estimates from the U.S. Census Bureau. UDOT is continually looking for ways to meet current and future transportation needs while maintaining the existing highway system in good condition.

The following list highlights some of UDOT’s most impactful projects for 2021:

Salt Lake, Summit and Tooele counties:

  • Bangerter Three Interchanges – Salt Lake County, $221 million: UDOT is building new freeway-style interchanges on Bangerter Highway at 6200 South, 10400 South and 12600 South. This is a continuation of UDOT’s multi-year effort to upgrade Bangerter Highway in order to meet the traffic demands of western Salt Lake County. Construction began in May 2020 and most of the project is expected to be completed by December. 
    Expected impacts: Drivers can expect the east/west closure of 12600 South at Bangerter Highway to remain in place until August, with reduced speeds along the detour routes. 6200 South remains closed to east/west travel across Bangerter Highway for cyclists and pedestrians through July. Drivers should also plan for an east/west closure of 10400 South at Bangerter Highway from May to November.
  • I-80 & I-215 Renewed; Salt Lake East – Salt Lake County, $146.5 million: UDOT is repaving I-80 between 1300 East and 2300 East, and the I-215 east belt between 3300 South and 4500 South. A new lane will also be added to eastbound I-80 between 1300 East and 2300 East, and the 1300 East, 1700 East and 2000 East bridges along I-80 will be demolished and reconstructed. Construction for the project will begin as early as this May and will continue through 2022.
    Expected impacts: Drivers can expect lane restrictions on I-80 and I-215 overnight and on weekends, as well as at least two overnight closures of I-80 during bridge work.
  • S.R. 248; S.R. 224 to U.S. 40 – Summit County, $3.1 million: UDOT will extend the life of the pavement and provide a smoother driving surface along S.R. 248 by repaving the highway from S.R. 224 to the U.S. 40 interchange. This project is also upgrading a series of pedestrian ramps and restriping the corridor to add a westbound shoulder-running bus lane for about 2 miles from U.S. 40 to Comstock Drive. Construction is expected to start in June and continue through fall. 
    Expected impacts: Drivers can expect daytime lane closures and possible flagging throughout construction. 

Davis, Weber, Morgan, Cache, Rich, and Box Elder counties

  • I-15 Davis-Weber Express Lanes – Davis and Weber Counties, $163 million: UDOT is widening I-15 to extend the Express Lanes from Layton Parkway to Riverdale Road. The project is also building new, widened bridges at Church Street and 200 South and repaving and widening bridges at five additional locations. Additionally, crews are extending the on-ramp from Layton Parkway to Hill Field Road, installing new ramp meters at high-traffic on-ramps and replacing concrete panels between Hill Field Road and I-84. Construction began in summer 2018 and will continue through fall.
    Expected impacts: The project will maintain three lanes of traffic on I-15 during daytime hours, Monday through Saturday, but drivers should expect overnight and weekend lane closures as well as lane splits, shoulder work and other changing traffic conditions.

  • S.R. 53; 24th Street Viaduct Rehab – Weber County, $7.2 million: Crews will extend the life of the 24thStreet viaduct by repaving from A Ave. to Lincoln Ave over the Union Pacific railroad yard into downtown Ogden. This project will also enhance pedestrian access by converting stairs to an ADA-compliant ramp and improve drainage on the viaduct. Construction began earlier this month and is scheduled to be complete in early September. Expected impacts: Drivers can expect the viaduct to be reduced to a single eastbound one-way lane with pedestrian and bicycle access restricted. They should also plan for seven overnight closures of the viaduct, as well as one weekend closure.

Utah, Juab, Wasatch, Duchesne, Uintah, and Daggett counties

  • U.S. 40; Starvation Reservoir Bridge Preservation – Duchesne County, $4.2 million: UDOT will extend the life of the road and provide a smoother driving surface along the Starvation Bridge on U.S. 40 in Duchesne County. Crews will repave the concrete surface of the bridge and the bridge barriers and will apply a polymer seal to help the bridge surface resist wear. Construction began earlier this month and will continue through late October. 
    Expected impacts: Drivers can expect one-way traffic and heavy delays throughout the project.
