All Lanes Now Open on West Davis Highway, Utah's Largest Highway Project

SALT LAKE CITY, UT — The Utah Department of Transportation (UDOT) celebrated the opening of all lanes on the new 16-mile West Davis Highway with a community fun run/walk/bike event. More than 2,500 people joined elected officials and UDOT representatives on the two-mile event on the project’s new road and trails.

When construction began in May 2021, UDOT officials estimated that all lanes of the new highway (SR-177) would be open by summer 2024. That timeline was shortened, with the new West Davis Highway opening several months early.

“There has been a concerted effort to open up this new highway as soon as possible because we know it will immediately make a huge difference in people’s lives,” UDOT Executive Director Carlos Braceras said. “People need different options to get where they want to go in the way they want to get there, and this project represents our commitment to accomplishing this mission.”

The West Davis Highway is a 16-mile, four-lane divided highway designed to improve access to and from western Davis County. The highway runs from I-15 near Glovers Lane in Farmington to the future extension of S.R. 193 and 4500 West in West Point.

The West Davis Highway is expected to reduce delays by more than 30 percent on local roads west of I-15. Six new interchanges have been built to connect to I-15 and local roads:

  • I-15/Legacy Parkway in Farmington
  • 950 North in Farmington
  • 200 North in Kaysville
  • 2700 West in Layton
  • 2000 West in Syracuse
  • Antelope Drive in Syracuse

In order to move people as well as vehicles, West Davis has also added nearly 10 miles of new trails and now connects several existing regional trails, such as the Emigration Trail with the Legacy Parkway Trail. These new trails provide additional opportunities for recreation users as well as bicycle commuters, helping them get where they want to go.

The project also is preserving 1,100 acres of wetlands near the Great Salt Lake to help safeguard the environment.

The West Davis Highway is one of several projects planned to upgrade the transportation system in northern Utah to meet current and future needs. This is especially important because the number of homes in Davis and Weber counties is expected to increase by 65 percent by 2040.

Finish work on the West Davis Highway will continue into the summer with occasional lane closures while crews complete weather-dependent tasks like additional paving, seeding, and other punch list items.

A future phase is planned to extend the highway to 1800 North in West Point. Long-term transportation plans detail extending the West Davis Highway through Weber County and connecting back to I-15. An environmental study to extend West Davis to 1800 North in West Point will begin in spring of 2024.
