FOLLOWUP: Dates set for West Seattle low-bridge closure – April 19 through April 28

**UPDATE: The dates are now April 20-29**

(Low bridge, SDOT traffic camera)

When SDOT first sent the alert last Friday that a low-bridge closure was ahead, it was described as likely being for “about a week” during the window of April 19-28. Today, an update from SDOT – the bridge is expected to be closed to surface traffic for that entire 10-day window:

From Friday, April 19 through Sunday, April 28, the Spokane St Swing Bridge (low bridge) will temporarily be closed to people driving, walking and biking. This closure is necessary because the Seattle Department of Transportation crews have to move the control tower wires from the West Seattle Bridge (the high bridge) to a new underground conduit below the West Duwamish Waterway and replace the control system. These wires are connected to the hydraulic system that opens and closes the bridge. The West Seattle Bridge (high bridge) will remain open during the low bridge closure.

Travelers will need to detour to other routes. During the closure of the low bridge, here are options for reaching your destinations:

Riding the bus: Buses provide a reliable option for travel across the Duwamish Waterway via the West Seattle Bridge (high bridge). They accommodate people walking, biking, and rolling, offering the fastest route without driving. Use King County Metro’s trip planner for route and schedule details.

Riding the Water Taxi: The West Seattle Water Taxi offers direct service to downtown Seattle and operates seven days a week. Large vessels can accommodate up to 26 bikes.

Driving/Carpooling on the West Seattle Bridge (high bridge): The West Seattle Bridge (high bridge) remains open for drivers with no vehicle access restrictions. Note that pedestrians and cyclists cannot use this bridge.

Walking, biking, and rolling: For people who bike, walk or roll, there are several other routes to get around the closure. Check out the SDOT Bike Map to find available bike facilities. For people who walk or roll, we recommend utilizing public transit to reach your destination.

We are offering assistance to people impacted by the closure to use transit with a rewards code available through the TransitGo app. For detailed instructions on how to access this reward, go to this link.

For more detailed information about the closure and how to get around, visit SDOT Blog.

There’s other work ahead too over the next two years that will require “short-term closures,” including more cylinder overhauls. More info about the bridge’s ongoing work is here.

    This seems like extremely short notice for a 9 day closure. Sucks to be a bike commuter. The two free water taxi rides (transit go) doesn’t seem like a big help for the extra fees needed.

      Transit go (see the link) gives you two free fares per day.

    I’d think they ought to be posting signs along the pathway at both end of the bridge now, this week, to announce their upcoming closure. I’m a huge fan of WSB, but not everyone reads it. This affects several hundred cyclists each day (per the bike counter machine).

      I asked SDOT a few followup questions (will be updating above) including re: signage. They said they’ve put up “yard signs.” Where, they didn’t say, further followups to come.

      • Eddie April 9, 2024 (6:16 pm)

        No signs in sight at noon today.

          I saw one, it was like one of those lawn signs for youth soccer or political candidates. Said something cute & cryptic like “Seattle don’t go low” or something like that. Not so easy to figure out the meaning. It was near where the fishermen illegally park on the bike trail there where they go to snag salmon.

    I question the reliability of Metro in particular routes 56 and 57 that are constantly being cancelled.  Is Metro going to assure no cancellations during the low bridge work?

      That’s been going on for about 5 or 6 years, since before the pandemic. I’m pretty sure it’s the first line to get dropped when there are staffing shortages.

    Could they at least acknowledge that the other bike routes are substantially longer?  Like sure when the Suez Canal is closed, “other routes are available” but they are categorically worse.

    • Josh April 9, 2024 (8:00 pm)

      This would require the city and it’s citizens to care about alternate transportation and what that really means. But sadly our district gleefully elected a guy who says we are “good on bikes” in terms of infrastructure at a time when we desperately need a focus on true emphasis of multi modal transportation options that improve the health of the individual, the community and the planet. 

      • Sarch April 9, 2024 (8:57 pm)

        But I figure that’s why they are offering people (cyclists) a free water taxi option instead? 

    • bill April 9, 2024 (8:22 pm)

      Indeed the 1/2 mile or so across the low bridge to E Marginal becomes a 6 mile trip via the 1st Ave bridge. That’s easily an extra 40 minutes when you consider the lousy pavement in south SODO, numerous intersections and traffic lights, and wayfinding confusion. That SDOT “bike” map is a joke. Tip to SDOT (and warning to cyclists who don’t know SODO): Sharrows on a four-lane high speed arterial with choke points like 1st do not make a bike facility.

      • Jay April 11, 2024 (12:50 am)

        Yeah. I’m driving that week because I have no interest in being roadkill.

        • Pleasantville April 11, 2024 (1:54 pm)

          Why not take your bike on the water taxi or bus, for free?

  • Rooster April 9, 2024 (9:21 pm)

    I used the Transit Go free trips the last time the low bridge was closed for an extended period. Was able to load my bike and trailer onto the boat with no issues. It was actually pleasant. 

  • Admiral-2009 April 10, 2024 (1:50 pm)

    I just rolled over the lower level bridge, still no pending street closure warning signs.

  • Jay April 11, 2024 (8:34 am)

    I’m curious where some people are “looking” for the closure signs. I have seen several signs all over including many on Avalon, Delridge and Admiral just to name a few. They look like political yard signs and are very similar to the ones from the last bridge closure. 

  • Flivver April 11, 2024 (6:26 pm)

    WSB. For the last 2 nights KIRO has stated the closure starts tomorrow night-the 12th.

Sorry, comment time is over.
