PLAN AHEAD: Weekend closures, lane restrictions impact SR 99, I-5 and I-90

SEATTLE -- It's going to be a busy weekend around Western Washington, and there are many road closures that could impact your plans June 22-25.

One of the closures with the biggest impact -- southbound SR 99 will be closed starting Friday night through Sunday at 6:00 a.m. The closure is from the Battery Street Tunnel all the way to South Spokane Street.

Crews are using the closure to start preparing to transition from the Alaskan Way Viaduct to the new SR 99 tunnel which opens later this fall.

WSDOT created a handy map showing what events are happening this weekend and where you can expect extra traffic.
