Alaskan Way Viaduct reopens early, Aurora Avenue North remains closed

Posted on Sep 30 2013 3:43 PM

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 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 while crews working for the City of Seattle’s Mercer Corridor Project install a sewer line beneath Aurora Avenue North.

Travelers should anticipate congestion north of downtown Seattle on Sunday and give themselves extra time to reach their destination.

All lanes in both directions of SR99/Aurora Avenue North will be closed between the south end of the Battery Street Tunnel and Valley Street from 11 p.m. Friday to 5 a.m. Monday. Mercer Street, Broad Street and the I-5 on- and off-ramps at Mercer Street remain open.
