HEADS UP, AGAIN… Westbound SR 18 closing April 30-May 4th

We’re back with another weekend closure at the I-90/SR 18 interchange, this time on the westbound side. In addition to the SR 18 closure, the westbound I-90 off-ramp to SR 18 and Snoqualmie Parkway will also be closed, so plan ahead if you’re traveling through the area.

WHAT TO EXPECT THIS WEEKEND:

• Starting at 9 p.m. Thursday, April 30^th westbound SR 18 will fully close between Issaquah-Hobart Rd and I-90
• By 5 a.m. Monday, May 4^th at least one lane is expected to reopen but expect additional work to continue in a single lane as crews reinstall guardrail, curbing and stormwater drains
• The WB I-90 off-ramp to SR 18 and Snoqualmie Parkway will be closed

WHAT THIS MEANS FOR DRIVERS:

Seattle-area travelers should prepare for a busy weekend on the roads.

This westbound SR 18 and WB I-90 off-ramp closures will continue to impact travel near the I-90/SR 18 interchange. Expect congestion in the area and delays along nearby routes.

Passenger vehicles should use alternate routes and plan for added travel time. To reach Snoqualmie Parkway or the SE 104th St area, follow the signed detour: continue westbound on I-90 to the High Point Way exit, then return to eastbound I-90 and exit at SR 18/Snoqualmie Parkway.

Issaquah-Hobart Road and city streets in Issaquah are NOT suitable for freight. During the eastbound SR 18 closures, freight traffic should use alternate routes or follow the signed detour on westbound SR 169 to northbound I-405, then take eastbound SR 900 to eastbound I-90.

This work is weather-dependent and may be rescheduled. Schedule updates will be available on the project webpage, WSDOT’s Travel Center map and the WSDOT mobile app.
