U.S. 95, Thorncreek Road to Moscow Project



The Federal Highway Administration (FHWA) has approved the three U.S. 95 Thorncreek Road to Moscow alternative/alignments recommended by the Idaho Transportation Department (ITD) for further study. The alignments are the same as those shown to the public at the January 2006 open houses – W4, C3 and E2.

Fall 2017 Update

The Idaho Transportation Department is preparing final design plans for the U.S. 95, Thorncreek Road to Moscow Project. The plans are expected to be available for review in the fall.

The Federal Highway Administration and ITD evaluated many alternatives for the new highway alignment, including western, central and eastern routes. The final eastern route (E2) was chosen after a multi-year environmental review process. ITD received a Record of Decision (ROD) from the Federal Highway Administration in March of 2016. The ROD gave ITD the authority to begin final design and purchase land.

A legal motion was brought against FHWA and ITD regarding the Environmental Impact Statement and Record of Decision for this project. In August 2017, the U.S. District Court for Idaho ruled against the motion in favor of FHWA and ITD.

The Idaho Transportation Department appreciates everyone who participated in the environmental process and submitted comments.
