Delays for US-95 travelers between Moscow and Lewiston this week

LEWISTON-Beginning this Wednesday, motorists using U.S. Highway 95 from Lewiston to Moscow will see greater delays at the Thorn Creek work zone as crews pour concrete.

A speed reduction will be in place over the Thorn Creek Bridge that will cause delays of approximately 20 minutes. Delays could be longer during commuting hours. Traffic will be slowed to a strict 5 mph over the structure to ensure vibrations do not impact the curing process for the high-strength concrete. Concrete work is expected to be done on Wednesday, with curing necessary on Thursday and Friday. Restrictions will be in effect, though there may not be active work on site.

Drivers are encouraged to plan ahead and avoid delays by taking State Highway 8 and then the Moscow-Pullman Highway in Washington as an alternate route.

Work at the Thorn Creek Bridge is one of the few remaining steps in completing the new four-lane section from Reisenauer Hill to Moscow. Construction began in 2022 to shift the curving, two-lane highway to the east and expand it to four lanes. The nearly $90 million realignment was funded partially by Governor Little's Leading Idaho program and was designed to be safer with a flatter grade, fewer curves and better access control.

Five miles of the new alignment opened to traffic in early July. This last mile is expected to be complete by November.
