Changes coming to westbound on-ramp at I-90, SH-41 Interchange next week

POST FALLS – 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

    The City of Post Falls is set to begin a pavement rehabilitation project on Spokane Street in early April that will impact travel routes and traffic detoured within the I-90 and SH-41 Interchange project. Full details about this upcoming project are available on the city’s website.
