For drivers who use SR 99 on a regular basis, take note: we’re just two weeks away from a four day closure of SR 99.
Both directions of SR 99 will be closed between South Spokane Street and Valley Street from 10 p.m. Friday, Aug. 22 to 5 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, but 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.
