Post Falls, Idaho – Beginning tomorrow night, the Idaho Department of Transportation (IDOT) will close the westbound I‑90 exit to State Highway 41 at Exit 7 from 8 p.m. to 5 a.m. each night through Friday. The off‑ramp will reopen each morning, with the final closure expected to end Saturday morning.

Detour routes for motorists

During the overnight closures, westbound traffic will be rerouted to the Seltice Way exit. Drivers entering westbound I‑90 in Post Falls toward Spokane will also encounter a closure on the State Highway 41 on‑ramp from 8 p.m. until 5 a.m. IDOT advises motorists to use Spokane Street to reach westbound I‑90 during those hours.

Additional lane shifts

In addition to the exit closures, IDOT reported that westbound traffic between Huetter Road and State Highway 41 will shift to the south side of the interstate. This temporary traffic pattern gives crews the space needed to begin construction of new westbound lanes in that corridor.

Long‑term construction plan

The work on the new lanes is part of a broader improvement program slated to continue through the next year. By moving traffic to the south side of the highway, the department can safely install additional pavement, shoulders and drainage while minimizing disruption to daily commuters.

What drivers should know

• Closure times: 8 p.m. – 5 a.m., nightly until Friday; final closure ends Saturday morning.
• Detour routes: Use the Seltice Way exit for westbound I‑90 traffic; use Spokane Street for the State Highway 41 on‑ramp.
• Traffic shift: Westbound traffic between Huetter Road and State Highway 41 will travel on the south side of the interstate.
• Purpose: To provide space for building new westbound lanes, improving capacity and safety.

IDOT urges drivers to plan ahead, allow extra travel time and follow posted signage. The department will monitor traffic flow and adjust detour routes as needed to keep the corridor moving smoothly.

Community impact

Local businesses and residents have been briefed on the temporary changes. While nighttime closures may inconvenience some commuters, the long‑term benefit of additional lanes is expected to reduce congestion during peak travel periods, supporting the region’s growing economy and preserving the quality of life for families who rely on I‑90 for work, school and recreation.
