COEUR d’ALENE — Work will start Monday to replace bridges on Interstate 90 where it passes over Pennsylvania Avenue near the exit for Sherman Avenue, according to an Idaho Transportation Department press release.
The two bridges were built in 1960 and are being replaced to ensure continued safe travel.
Traffic will be reduced to one lane in each direction and crossed over to the westbound lanes, as the eastbound structure will be closed and rebuilt first. Once the eastbound structure is complete, the westbound structure will be rebuilt, and two lanes of traffic will be shifted to the opposite side, the release said.
Pennsylvania Avenue will be closed underneath the bridges for the duration of the project, with traffic detoured to Elm Street. Both bridges over Pennsylvania Avenue are planned for completion in October.
Drivers and residents can also expect increased noise and vibration impacts during demolition of the old bridges and pile-driving of new support structures throughout construction.
Crews are scheduled to work Monday through Saturday.
