UDOT announces major projects for 2023 and reminds drivers to be safe in work zones as highway construction ramps up

With 217 construction projects around the state this year, UDOT urges drivers to stay alert and use caution in work zones

As the weather warms up, the Utah Department of Transportation (UDOT) is ramping up construction on highway projects across the state, and asking Utahns to be careful while driving through work zones.

In 2023, UDOT has 217 projects scheduled to start or already under construction, with a combined value of $3.2 billion. This means there will be 217 different work zones across the state where drivers will need to use caution and stay alert to keep themselves and construction crews safe.

“This is one of our biggest construction years, with major projects happening all across the state,” said Lisa Wilson, UDOT deputy director for engineering and operations. “We are working to help people in all parts of Utah stay connected to the things they care about: family, school, work, and recreation.”

Projects scheduled to start or already under construction in 2023 include a brand-new highway, new interchanges, widened freeways and highways, new paths for pedestrians and cyclists, maintenance to keep roads and bridges in good condition, and improved access to a new state park.


The major projects UDOT wants drivers to plan for this year include:

Bangerter Highway: Salt Lake County – $378.5 million

This project will construct four new freeway-style interchanges with on- and off-ramps at 2700 West, 13400 South, 9800 South, and 4700 South, eliminating stoplights at four more intersections for drivers on Bangerter Highway. Construction is scheduled to start this summer.

This project will also build a new trail system for pedestrians and cyclists. These improvements will help area residents get around more easily, whether they are walking, biking or driving.

In 2022, there were 1,297 work zone-related crashes on Utah roads, and 11 people lost their lives in those crashes. Warmer weather months, when more projects start due to the higher temperatures required for asphalt paving, are also when more crashes occur – June (138) and September (136) were the months with the most work zone crashes last year.

With all these work zones in place or starting up, UDOT reminds drivers to use caution, be alert and obey posted signs and speed limits. In construction zones, lanes can be narrow, pavement may be uneven, and crews and equipment may be working close to traffic.

“We are doing everything we can to make our work zones as safe as possible,” Wilson said. “We need your help to ensure everyone makes it home safely every day.”

Construction schedules are weather-dependent and subject to change.
