Press Release from Idaho Department of Transportation
POST FALLS, Idaho — 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 shifter to the north near central Avenue. Shifting the on- and off-ramps will provide space for crew 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.
