BUILD GRANT 2020: Teton Mobility Corridor Improvements


The Teton Mobility Corridor Improvements (TMCI) will implement a series of multimodal improvements along the ID-33/WY-22 corridor between Driggs, ID and Jackson, WY, connecting residents and visitors to many of the region’s economic generators, including Grand Targhee Resort, City of Driggs, City of Victor, Jackson Hole Mountain Resort, and the Town of Jackson. The project will include the development of two transit centers; a park-and-ride facility; completion of 8.5 miles of missing links in the pathway network; optimization of signals for transit vehicles; purchase of four regional commuter buses and two electric local buses for the transit fleet; and development of rural regional highway upgrades to improve safety and operations.
