The Mountain View Corridor, numerically designated as State Route 85 (SR-85), is an expressway currently under construction that will run along the western periphery of Salt Lake County and northwest Utah County in northern Utah. A spur of the eventual freeway to Interstate 15 opened in northwestern Utah County September 2011. Mountain View will start in Salt Lake City west of the Salt Lake City International Airport, diverging from Interstate 80, and end at SR-73 near Lehi. It will run north–south at 5800 West for most of its 35-mile (56 km) extent in Salt Lake County before curving southeastward toward SR-73 in Lehi. The spur between SR-85 (initially SR-68) and I-15 runs along 2100 North in Lehi`s street grid.
