The Alaskan Way Viaduct will be closed this weekend for its twice-yearly inspection.

Both directions of Highway 99 will be closed between South Spokane Street and the north end of the Battery Street Tunnel from 6 a.m. to 6 p.m.  Saturday and Sunday.

Drivers are advised to plan ahead and be prepared for congestion on Interstate 5 and surface streets through downtown.

The closure will allow crews to perform maintenance and thoroughly inspect the aging structure, as they do each spring and fall.  A WSDOT fact sheet has more information about keeping the viaduct safe while the tunnel to replace it is being constructed.
