Four-day closure on SR 99 just around the corner

With just over a week until State Route 99 closes for four days in Seattle, it’s time to get your travel plans in place. The upcoming closure is expected to cause backups on city streets and increase delays on Interstate 5.

Both directions of SR 99 will be closed between South Spokane Street and Valley Street from 10 p.m. Friday, Aug. 22 to5 a.m. Monday, Aug. 25. The section of SR 99 between Spokane Street and the south end of the Battery Street Tunnel will reopen just before the Monday morning commute, however, the highway will remain closed through the tunnel to Valley Street until 5 a.m. Wednesday, Aug. 27.

During the closure, contractor crews will demolish and replace the section of SR 99 that crosses above Broad Street. They will also replace more than 80 damaged or cracked concrete road panels between South Spokane and South Holgate streets.
