Creating a 2.8-mile corridor between Interstate 15 and Mountain View Corridor in Lehi, just south of Salt Lake City, to offer a faster route for drivers in northwest Utah County. Work on the project is expected to continue into late 2028, and the design-build contract was awarded to a partnership between Ralph L. Wadsworth Construction and WW Clyde.
