I-90 Lane Reductions and Upcoming Closures | Oct. 16–Nov. 15

I-90 lane reductions: Oct. 16–21

Starting early Friday, Oct. 16, I-90 between Northwest Boulevard and US-95 will be reduced to one lane in each direction, 24 hours a day, through late Wednesday, Oct. 21. Significant congestion and delays are expected, including during weekday commutes.

• Use alternate routes and avoid the area if possible.

• If travel through the work zone is necessary, allow extra time.

• Crews will pave before winter to complete most I-90 work east of Northwest Boulevard this year and reduce construction impacts next year.

Traffic after paving

• Eastbound: Both lanes toward Montana will reopen after paving.

• Westbound: One lane will remain open while crews finish widening near the Northwest Boulevard on-ramp. Both lanes are expected to reopen by early November.

• Northwest Boulevard westbound off-ramp: Remains closed until both westbound I-90 lanes reopen to reduce merging and lane changes.

Westbound traffic shift near Huetter Road

Next week, both westbound lanes between Huetter Road and SH-41 will shift to the south side of I-90 for approximately one year while crews build the expanded lanes.

Upcoming closures at Huetter and Atlas roads

Both roads will temporarily close beneath I-90 for demolition of the existing westbound bridges.

• Huetter Road: Closed Oct. 26–Nov. 1. Use Atlas Road as an alternate.

• Atlas Road: Closes Nov. 1 for up to two weeks. Use Huetter Road as an alternate.
