Starting next week, the Idaho Transportation Department will begin to resurface an 8-mile stretch of Interstate 90 to preserve and extend the life of the roadway, enhance safety, and deliver a smooth ride for travelers. This will be a two-year project, ending in fall of 2026.
This project will also add illumination near the top of Fourth of July Pass, improve the highway drainage system and replace several miles of concrete barrier.
Work on both eastbound and westbound lanes of traffic will occur simultaneously in small, continuous sections of the 8-mile work zone. There is a scheduled break in construction over winter between the 2025 and 2026 construction seasons, but if mild winter weather prevails, some work may continue to advance the project ahead of schedule.
TRAFFIC IMPACTS
- Lane reductions
- Speed reductions
- Lane width restrictions
- Intermittent flagging possible
During construction, drivers can expect traffic to be reduced to a single lane in each direction with reduced speed limits and lane width restrictions. Intermittent flagging may also be necessary at on- and off-ramp locations.
Work will be conducted during daytime hours; however, lane and speed restrictions will remain in effect at all times through the construction season.
This project is one of several that will dot the I-90 corridor from the Washington state line to the Silver Valley in 2025, including the I-90 expansion project between Post Falls and Coeur d’Alene, the I-90 State Highway 41 Interchange project, and the I-90 bridge replacement project near Cataldo.
