COEUR D’ALENE – Drivers should plan for delays this Sunday on eastbound Interstate 90 between Post Falls and Coeur d’Alene as crews complete striping in the work zone to expand the freeway to four lanes. Work will begin around 7 a.m., with traffic reduced to one lane and the speed limit lowered to 45 mph throughout the day.
“This is one of the last weather-dependent tasks we have to complete before winter, and this weekend just might be our last chance to do it with the conditions needed,” Project Manager Tom Trutter said. “We’re doing it Sunday when traffic is lighter, but congestion is still expected so we’re asking drivers to plan extra time and be patient through the work zone.”
Due to the temperatures needed for the paint to dry properly, this work cannot be done overnight.
In addition to this work, new variable speed limit signs will soon be activated along the I-90 corridor during the expansion project. These digital signs allow ITD to adjust posted speeds for safety when crews are working close to traffic. As a reminder, drivers are required to follow the posted speed limit at all times and should not rely on in-car navigation systems or GPS devices through the work zone, as they may differ from the posted speed.
This five-mile stretch of I- 90 from State Highway 41 to U.S. Highway 95 is the most heavily traveled and congested area in the corridor. This is the first construction project to advance from the I-90 Corridor Study from SH-41 to 15th Street to enhance safety and add capacity to support future traffic volumes.
Construction began in August of 2025 and is expected to be complete in 2029.
