  • The eastern section, which includes the Coeur d’Alene area, is anticipated to be complete by spring 2024.

Widening Design

Widening plans for I-90 from SH-41 to US-95 are being advanced to construction in 2024 to target the most congested section first. The project does not include updating any interchanges. Improvements are anticipated take three construction seasons to build.

Corridor Study

  • The western section, which includes the Post Falls area, is on hold until additional funding is identified to complete remaining analysis and propose recommendations. 
    ITD and the city of Post Falls will host an open house this fall to gather feedback on preliminary alternative designs for I-90 and the primary routes in the Post Falls area. Feedback will be used for an update to the City’s transportation master plan.
