This project is to improve driver safety, traffic flow, and roadway structural integrity of US 20 between the Junction of SH 87 and the Montana state line, also known as Targhee Pass.

ITD is now initiating an environmental assessment (EA) to evaluate risks, benefits, opportunities, and costs associated with reconstruction of Targhee Pass (U.S. 20 between its junction with Idaho 87 and the Montana state line). Targhee Pass is a portion of the U.S. 20 corridor that has been evaluated as part of the U.S. 20 Safety Corridor Study.
