UDOT Widened I-80 to Ease Travel Between Salt Lake and Tooele Counties

Sept. 20, 2022

Tooele County, an area west of Salt Lake County, Utah is connected to Salt Lake City by Interstate 80 (I-80). As the population in Tooele County grows, increasing the number of people that commute between the two counties, there is a need to add capacity to I-80. When there is severe congestion or a severe crash, motorists have only two options: wait for things to clear or make a two-hour detour to the south. Utah Department of Transportation (UDOT) contracted with Arizona-based Sundt Construction on a USD 4.7 million project to widen the two-mile stretch of I-80, adding an extra lane between state road 201 (SR-201) and exit 99 while also providing the necessary roadway striping and signage. With the goal of enabling multidiscipline teams to share information and review design files, the I-80 project was one of UDOT’s first projects using Digital Twins and design review technology.
