What's Next

Scoping Report – ITD has published a scoping report summarizing public comments and issues to be evaluated in the Targhee Pass EA. This report is available under the "Helpful Resources" tab of the main navigation, or download by clicking here.

Impact Analysis – ITD is wrapping up the impact analysis, which is evaluating and assessing the impacts of each alternative.

Environmental Analysis Comment Period and Public Meeting – When ITD has completed the impact analysis, results will be shared with the public via the website, stakeholder working group, and a public meeting. At that time, ITD will be looking for your additional feedback and will provide another 30-day comment period. This is currently expected to occur in late summer 2018.

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.
