Travel Alert: West Seattle Low Bridge maintenance scheduled for weekend of May 29-31

The Seattle Department of Transportation (SDOT) will be working at night on the West Seattle Spokane Street Low Bridge the weekend of May 29-31.

We will be doing necessary maintenance work on the low bridge’s controls and communications systems that are used to operate the bridge.

The work will be done at night to minimize traffic impacts and because some of the systems need to be turned off during the maintenance activities.

We will be closing the low bridge to vehicle, bike, and pedestrian traffic while we are working at night because we will not be able to open and close the bridge in a normal manner.

As a result, roadway traffic, including freight and buses, will be detoured to the 1st Ave or the South Park bridges. The low bridge will also be closed to bicyclists and pedestrians, and emergency vehicles will have limited access across the bridge. Waterway traffic will be maintained. 

These restrictions will only be in place at night while we are working during the following hours:

  • Friday night: 8PM to 5AM
  • Saturday night: 6PM to 3AM
  • Sunday night: 6PM to 3AM (if needed)

During the day, transit, emergency vehicles, freight, bikes, and pedestrians will have access to the bridge.

Thank you for your patience and understanding while we do this important maintenance work.
