Drivers should plan ahead for the four-day closure of a portion of State Route 99, including the Viaduct, beginning Friday night. This will create backups on I-5 and nearby streets, so be prepared for a longer commute time. Road crews will replace 81 damaged or cracked concrete panels, repair an expansion joint, and demolish and replace the section of SR 99 over Broad Street, which will become part of the permanent connection between the SR 99 tunnel’s north portal and a new surface street section of Aurora Avenue North.
- At 10 p.m. Friday, Aug. 22, crews will close both directions of SR 99 between South Spokane Street and Valley Street. However, due to the Seahawks game, northbound SR 99 will remain open at South Royal Brougham way and southbound SR 99 will remain open from the Columbia Street on-ramp until midnight.
- At 5 a.m. Monday, Aug. 25, crews will reopen both directions of SR 99 south of the Battery Street Tunnel. Both directions of SR 99 will remain closed between the south end of the tunnel and Valley Street.
- At 5 a.m. Wednesday, Aug. 27, crews will reopen both directions of SR 99 between the south end of the Battery Street Tunnel and Valley Street.
Metro Transit will reroute a number of buses, including the D Line through Ballard, and the 5 local and express, 28 express, and RapidRide E Line along Aurora Avenue. Check Metro’s Alerts page for more information.
