Next week, as part of the Interstate 90 and State Highway 41 Interchange project, the access point for the westbound I-90 on-ramp is being shifted to the north near Central Avenue. Shifting the on- and off-ramps will provide space for crews to continue working on the new center of the future interchange.
This shift will allow southbound traffic from SH-41 to merge seamlessly onto the on-ramp, rather than requiring drivers to make a dedicated right turn.
Because of this change, starting next week northbound drivers on SH-41 will no longer be able to turn left onto the westbound on-ramp.
Northbound drivers on SH-41 wishing to access westbound I-90 will be detoured north to 16th Avenue where they will make a U-turn and then return south along the highway until they merge onto the new westbound temporary on-ramp.
This closure will be in effect through fall 2025.
As a reminder, there are several ongoing closures related to the I-90/SH-41 Interchange project that were shared with the community in early March:
- The westbound off-ramp remains closed through fall 2025 while crews construct a new straight off-ramp and the single-point urban interchange. Traffic is detoured to the Seltice Way Interchange at Exit 6. Click here for detour map.
- Central Avenue will remain closed through late fall while crews continue to widen SH-41. Business access has changed (view map).
This project also includes improvements to SH-41 and surrounding local roads. Construction for this project is expected to be complete in 2026.

City of Post Falls Spokane Street Pavement Rehabilitation Project
As part of ITD’s ongoing efforts to keep the public informed about construction activities and travel impacts, we would also like to share information regarding an upcoming pavement rehabilitation project on Spokane Street that is set to begin on April 7.
This work will reduce traffic to one lane in each direction and will occur in several phases. During some of these phases, there will be intermittent closures of the I-90 on- and off-ramps at Spokane Street.
Full details about the City of Post Falls project are available on the city’s website or by contacting the City of Post Falls Projects Division.
While the ITD and City of Post Falls projects are independent of one another, both agencies are committed to working together to share information with the public. Information about the city’s project and its potential impact on travel routes within the I-90/SH-41 project area will be communicated through email updates, the Idaho 511 system, and ITD’s social media channels as part of our ongoing I-90, SH-41 outreach.
Anyone interested in staying informed is encouraged to register for email updates, utilize the free Idaho 511 system, of follow ITD’s social media channels @idahoitd.
