US-95: Thorncreek Road to Moscow

Expanding the highway to four lanes will not only add capacity and reduce travel times but also significantly improve safety.

Once a permit is obtained from the Army Corps of Engineers, ITD will solicit bids for construction in late 2019.

Project overview

About 6.5 miles of highway will be expanded to four lanes divided by a 34-foot median in the rural section. Shoulders will be widened, curves will be made easier to navigate and the grade will be less steep. New ditches will keep precipitation from gathering on the roadway, and a 30-foot clear zone will provide a safe area if a vehicle goes off the road.

County road intersections will have right and left turn lanes, and some current access points will be combined to limit the number of new intersections and driveways.

In the urban section just south of Moscow, a center turn lane, curbs, gutters and sidewalks will be added.


Details, such as the timing of work, will become available once ITD bids the project for construction. A bid will be solicited once the right of way process is complete and ITD has a permit from ACOE.

Construction is expected to take two years, with most work in the first year to take place off alignment without impacts to traffic.

Expansion gets green light

The Ninth Circuit of Appeals ruled in favor of ITD in the latest appeal. Work will continue on final design plans and acquisition of right of way.


Following the December 2018 court decision, ITD will continue right-of-way acquisition and submit a 404 permit application with the U.S. Army Corps of Engineers. After those two steps are completed, the project can be put out for construction bids.
