Update: Saturday, Oct. 5, 5:30 p.m.
Seattle's Alaskan Way Viaduct reopens early after inspection, Aurora Avenue North at Mercer Street remains closed
Highway crews reopened the State Route 99 Alaskan Way Viaduct Saturday night after an inspection closure; however, all northbound viaduct traffic must exit at Western Avenue until 5 a.m. Monday.
The viaduct was closed until 5:00 p.m. Saturday for a semiannual inspection. Crews completed detailed inspections and maintenance work ahead of schedule, so the viaduct will not close Sunday as planned.
A section of SR 99 north of downtown, including the Battery Street Tunnel, will remain closed until 5 a.m. Monday.
Semiannual Alaskan Way Viaduct inspection, utility work to close SR 99 through Seattle this weekend
Drivers should plan for backups on SR 99, choose alternate routes
SEATTLE – Item for weekend to-do list: check the schedule for planned closures of State Route 99 before heading to, or through, downtown Seattle.
The Washington State Department of Transportation will close the SR 99 Alaskan Way Viaduct for a semiannual safety inspection from 5 a.m. to 6 p.m. Saturday and 6 a.m. to 6 p.m. Sunday. Additionally, crews working on the City of Seattle’s Mercer Corridor Project will close a section of SR 99 north of downtown, including the Battery Street Tunnel, to install a sewer line from 11 p.m. Friday to 5 a.m. Monday.
