With three games and major roadwork, prepare for delays on downtown highways and city streets
While the summer season may seem mostly over, we still have vital work to do to keep the highways in the Seattle area running smoothly. Add home games for the Sounders, Mariners and Huskies to the mix and it's going to be a busy traffic weekend for the highways and city streets around the region.
So what's closed this weekend? Here's what you need to know:
South Dearborn Street closure
Contractor crews are preparing to remove two small sections of the Alaskan Way Viaduct on South Dearborn Street near the stadiums. This work will close South Dearborn Street for up to ten days starting on Thursday, Sept. 12 and narrow First Avenue South to two lanes on either side of the intersection to create a safe work zone.
This work will affect those headed to the stadiums for the Sounders and Mariners games. During this time, consider alternate routes, including exiting SR 99 at Spokane Street, as well as transit, carpooling or bicycling.
SR 99 tunnel maintenance closures
Typically the monthly overnight maintenance closures of the SR 99 tunnel are in one direction, but we need to do a structural inspection of the tunnel's double-deck highway. To do that, we need to turn off the air exhaust system, so for the safety of the public we will close the tunnel in both directions.
Here's the schedule:
- From 10 p.m. Friday, Sept. 13, to 8 a.m. Saturday, Sept. 14 – Both directions of the SR 99 tunnel will fully close.
- From 10 p.m. Saturday, Sept. 14, to 8 a.m. Sunday, Sept. 15 – The northbound SR 99 tunnel will close.

Northbound I-5 lane reductions at 85th Street
Two lanes of northbound I-5 at 85th Street will close from 10 p.m. Saturday to 10 a.m. Sunday. We are repairing concrete panels near the area. During this weather-dependent work, the northbound I-5 express lanes will remain open overnight.
We've had our fair share of roadway closures this summer and this weekend is no exception. The best thing you can do is plan ahead, use alternate routes in some circumstances and stay updated using our online tools.
