WEEKEND ROAD CLOSURE: Here’s what’s being done on Sylvan Way

As noted in today’s morning traffic watch, one of West Seattle’s major east-west routes, Sylvan Way, will be closed much of this weekend, without major advance notice aside from sparse signage. Today SDOT was finally able to tell us this is a Seattle Public Utilities project, and we have obtained more information through SPU spokesperson Sabrina Register:

This is SPU drainage crew work. They are responding to some localized flooding issues that were reported by the community last year. SPU is installing one inlet and one catch basin and needs to trench across the street to connect to them to the drainage mainline.

This work will occur Saturday and Sunday, 8 am to 5 pm, and a detour will be in place. Outside of working hours, the crew will be able to reopen the roadway and allow traffic on Sylvan.

The work will be focused in the 6900 block of Sylvan Way [map]. It also means a reroute for Metro Route 128 – here are those details.

    Thanks for digging up the info!Any idea if local access will be allowed to High Point and Sylvan Ridge Townhomes or does everyone have to make their way to/from via side streets that are east of 35th?Route 128 link is missing the end of the URL .pdfReroute Template – enter title here (kingcounty.gov)

      This is every shred of info I could get. We are going to try going over in the morning (the back way) and walk in to see what’s allowed. We have at least one source on Sylvan too …

    The community has also been asking for a crosswalk and sidewalks along Sylvan Way.

    so no official statement on why this info was so poorly communicated?

    If they don’t have  people at the bottom of Sylvan restricting traffic, this is going to be a disaster…

    “Detour will be in place.” I don’t think so. Everyone trying to get down the hill is forced to turn into Sylvan Ridge with no signs detouring how to get out. Mass confusion. Not to mention dangerous.

      Agreed, not sure who the real project manager for SPU was on this project but they completely bungled communication or just lazily didn’t care about setting up a proper detour.

        I spoke with the manager on site of the SPU project today and was told the plan was submitted to SDOT, who came back with zero traffic concerns.

    While they are at it, they should also fix the deep pothole in the middle of that road by the cemetery. You can barely see it at night.

Sorry, comment time is over.
