The Idaho Transportation Department will begin work to replace damaged concrete in Pocatello on Yellowstone Avenue (U.S. Highway 91) on Monday, Oct. 5. Work will begin Monday evening at the intersection of Yellowstone Avenue and Flandro Drive, with several detours near Costco necessary to create a safe work zone for crews.
What to expect:
- No right turns onto Yellowstone Avenue from eastbound Flandro Drive (leaving Costco). Motorists will instead use the parking lot exit to the south.
- No left turns onto Flandro Drive (heading toward Costco) from northbound Yellowstone Avenue. Motorists will use Quinn Road and Hiline Road to detour around the closure.
On the southwest side of the intersection (near Costco), the pedestrian crosswalk to cross Yellowstone Avenue will be closed. Pedestrians will detour to Pearl Street to reach their destination. Traffic is expected to remain in this pattern through October, and the overall project is anticipated to be complete in 2027.
Yellowstone Avenue is a main thoroughfare in the area, providing access to many businesses, residences and services. Several areas of Yellowstone Avenue have deteriorated after years of heavy use, and the new concrete is expected to serve the community for 20 years.
