The US 93 Ninepipe Corridor Feasibility Study kicked off in June 2021 and was completed in March 2023. This study evaluated the feasibility of a project within the Ninepipe segment and does not guarantee future design or construction efforts.

An initial review of relevant conditions within the study area was completed in late 2021 to identify conditions that have changed since the evaluations conducted for the 2008 SEIS. The feasibility evaluation occurred in 2022 to consider costs, impacts, and construction feasibility relating to the preferred alternative. Feasibility study documentation was developed, with a final report completed in March 2023.
