West Davis Corridor Design-Build

Farmington Bay Constructors Joint Venture, with Ames Construction as the managing partner, built a new 16-mile, four-lane divided highway in Davis County, Utah. Now known as West Davis Highway, the corridor was opened to traffic in early January 2024, several months ahead of schedule.   

Stretching from I-15 in Centerville City to SR-193 in West Point City, the highway relieves traffic congestion in one of the fastest growing areas of the country. Construction included new northbound and southbound lanes, five freeway-style interchanges, 21 roadway bridges, and four pedestrian bridges. The project also preserved 1,100 acres of wetlands near the Great Salt Lake, a crucial habitat for breeding and migratory birds.

Because this is a new corridor, the project didn’t require traffic maintenance. However, minimizing truck traffic on existing city streets during the project was a priority. Crews constructed a haul road the length of the project using geotextile. The road was built on undisturbed ground, without stripping vegetation, which allowed for faster construction and minimized the risk of soft subgrade. Some 1.7 million tons of material were trucked to the project to surcharge the fill areas, reducing settlement after construction.

Additional work scope included retaining walls, drainage systems, two equestrian crossings, and 10 miles of new trail and trail connections to create a consolidated trail system for the region.
