US-95: Thorn Creek Road to Moscow
Expanding the highway to four lanes on a new alignment will not only add capacity and reduce travel times but also significantly improve safety.
Construction is expected to begin in the spring of 2022.

New alignment
Look for the E-2 route
Envision the new route
The new alignment will tie in at Reisenauer Hill, where the current four-lane section ends, and reconnect near the grain bins on the south end of Moscow.
Compared to the existing route, after construction US-95 will ascend at a more gentle grade up Reisenauer Hill to the prairie below Paradise Ridge. The highway will cut through small hills below the ridge to maintain a consistent grade, cross over Eid Road via a bridge and descend into Moscow.
Generally, US-95 will be shifted to the east less than three-quarters of a mile, and ITD is in the process of relinquishing its jurisdiction of what will be old US-95 to North Latah Highway District.
With a flatter grade and fewer approaches, the new route will provide safer travel between Moscow and Lewiston.
Map of new route (E-2)Design details
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.
Construction
Details, such as the timing of work, will become available once ITD awards the project to a contractor.
Construction is expected to take three years, with work commencing at the southern end where the new alignment will tie in with the old at Reisenauer Hill.
