Weekend Advisory for February 2-4 – Battery Street Tunnel Closure, #99StepForward, and More!

Cheers to the Freakin’ Weekend!

It’s been another great week here in Seattle. As Seattleites continued to squeeze and help reduce traffic congestion during our city’s busiest commuter hours, crews worked around the clock to get the SR 99 tunnel ready to open before the Monday morning commute on Feb. 4. And here we are at Friday again with a whole weekend ahead – what’s better than having something to look forward to AFTER the weekend, on a Monday?!

As you make your weekend plans around the city, here’s a look ahead to some weekend events that may affect traffic:


Battery Street Tunnel Closure, 10 PM tonight

Expect traffic detours for SR 99 / Aurora Ave N at Valley Street until the new SR 99 tunnel opens on Monday morning. Please be aware of these changes to traffic and plan ahead if you’ll be heading either northbound or southbound on Aurora Ave N.
