Motorists traveling through Post Falls on Interstate 90 should prepare for traffic disruptions beginning Wednesday, July 8, as the Idaho Transportation Department opens a newly reconstructed eastbound on-ramp and initiates overnight work on the I-90/SH-41 interchange upgrade.
The new eastbound on-ramp provides direct access to I-90 East from State Highway 41, marking the final component of the Single Point Urban Interchange (SPUI) reconstruction project. Drivers will encounter a revised traffic pattern at the interchange as crews prepare the site for the next phase of construction.
Overnight Closures and Work Schedule
Starting July 8 and continuing through the following week, the Idaho Transportation Department will conduct nighttime construction work between 8 p.m. and 5 a.m. each evening. During these hours, the I-90 eastbound off-ramp will be closed, and both the westbound off and on-ramps will be unavailable to traffic. Motorists should also expect lane closures on I-90 throughout the interchange during the work window.
Construction crews will position cones, barriers, and signage throughout the project area to guide traffic and maintain safety.
Timeline and Regional Impact
The I-90/SH-41 interchange upgrade is expected to reach completion by fall 2026. The project represents part of the Idaho Transportation Department’s broader investment in regional mobility and safety improvements across North Idaho. Commuters and travelers using the interchange during peak hours should allow extra time for navigation and remain alert to temporary traffic patterns.
For drivers seeking information on broader transportation priorities in the region, the Idaho Transportation Department recently opened a comment period on road and bridge priorities through July 31. Additionally, those interested in long-range transportation planning can review details on the Rathdrum Prairie Transportation Study, which enters its final input phase with an open house scheduled for July 8.
