Well, that will happen tonight (Friday) when the lower West Seattle Bridge closes from 8 p.m. until midnight so the US Army Corps of Engineers can dredge the Duwamish River floor.
So if you need to bike to West Seattle tonight, better do it before 8. Unless, of course, you’re in the mood for a nice long bike ride all the way down to the 1st Avenue Bridge (or you can catch a bus, though the bike slots might be in high demand).
Details from SDOT:
The Spokane Street Bridge will be closed to motor vehicles 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 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.
Note to bicyclists and pedestrians:
Bicyclists and pedestrians are advised to cross the Spokane Street swing bridge before 8 p.m. on Friday. If this is not possible, there are two alternatives.
Pedestrians and bicyclists may want to consult metro bus schedules. You may load your bike on a bus; however, the number of buses after 8 p.m. and bike carrying capacity of each bus is limited. For information about bus service, see Metro Online, www.kingcounty.gov/metro, or call 206.553.3000.
The alternate bike route uses the First Avenue South Bridge, although this is quite a long distance south of the Spokane Street swing bridge. The First Avenue South Bridge sidewalk can be accessed via the Duwamish Trail on the west side of the river. On the east side of the river, the bridge sidewalk begins at the intersection of First Avenue South and South Michigan Street underneath the bridge approach.
