EA Overview

ITD and FHWA evaluated a number of possible alternatives to improve roadway structural integrity, traffic flow and safety of the Targhee Pass segment of U.S. 20. The EA summarizes the impacts of each alternative, and identifies Alternative 3 as the preferred alternative.

Roadway improvements included with Alternative 3 (and all of the build alternatives) are:

  • An additional travel lane in the uphill direction from SH 87 to the Montana State line
  • Shoulder widening from 5-feet to 8-feet
  • Hill cut to improve stopping sight distance
  • Left- and right-turn lanes into Big Horn Hills Estates entrances
  • Tree clearing to reduce shade
  • Road subsurface reconstruction and drainage improvements

In addition to the roadway improvements, Alternative 3 would include installation of an animal detection system throughout the 4-mile segment of U.S. 20. The system would alert drivers to the presence of animals. This alternative does not include crossing structures with wildlife fencing. Selecting Alternative 3 would require working with a vendor to install and then monitor and adapt the system over a period of several years to achieve a higher level of effectiveness. Monitoring would include evaluating the ability of the system to accurately detect animals, monitoring driver response, and monitoring road kill and crash data.

Targhee Pass Environmental Assessment

ITD is currently conducting an environmental assessment of the Targhee Pass segment of the corridor (U.S. 20 between its junction with Idaho 87 and the Montana state line.). ITD is evaluating risks, benefits, opportunities, and costs associated with reconstruction of Targhee Pass.
