4:35 PM: Just announced by SDOT:
The Spokane Street Bridge to West Seattle will be closed to motor vehicles, bicyclists and pedestrians on Friday night, Jan. 31, from 8 p.m. to midnight. The closure will allow a contractor working for the U.S. Army Corps of Engineers to dredge the channel where silt has accumulated. Drivers are advised to use the high-level West Seattle Bridge during this time.
The contractor will begin dredging tomorrow (Thursday) night, but will not need to close the bridge to motor vehicles until Friday night to finish the work. The channel will remain open for marine traffic.
ADDED 5 PM: Thanks to David and Bob for tipping us to this alert also just announced: “SPD will conduct rolling slowdowns on the SR 99 Alaskan Way Viaduct for filming operations. The rolling slowdowns will take place between the West Seattle Bridge and the Western Ave Exit from 9:00 a.m. to 11:00 a.m. on Sunday, February 2, 2014.”
ADDED THURSDAY: From an SDOT rep in response to the question of whether there will be any type of transportation to get people on foot/bikes around during the closure – since they can’t use the high-level bridge as an alternative – short answer: No. But the contractor might be able to take less time than the four-hour window. We’ll monitor the situation as best we’re able to on Friday night so we can publish an update when the bridge is back to regular operations.
