From SDOT today, an update on West Seattle Bridge work:

Last week, crews completed the hydro-blasting work. This created access points for the work platforms to hang from and openings in the bridge deck to access the inside of the bridge.

We’ve also been working to attach rigging that will hold the work platforms in place underneath the bridge. These components consist of 10- to 14-foot-long metal cables that are being fed through the holes in the bridge deck. Next, we’ll install stairs and scaffolding inside the bridge.

In the coming weeks, we’ll begin core drilling on the inside of the bridge at Pier 16, where we’ll install post-tensioning cables to reinforce the strength of the bridge’s concrete. We’ll also be relocating utility lines at this location to make room for the additional post-tensioning cables.

We’re continuing to build the work platforms, which we expect to will hoist up to the underside of the bridge in January. These platforms create a workspace to complete epoxy injections and carbon-fiber wrapping on the outside of the bridge.

Heads up that there may be limited weekend traffic impacts on SW Manning St and E Klickitat Ave while we raise the work platform on the east side of the bridge – stay tuned for more details about timing in future updates.

Here’s an SDOT graphic showing where those platforms will go up:

The contractor’s project manager provided an in-depth briefing of the work plan at this month’s Community Task Force meeting (WSB coverage here).

    Looks like they’re out there working in the freezing cold, snow, and ice. If they would have gotten right to work when they were supposed to, they could be relaxing by now in front of the fireplace! (JK) :-)

    More seriously, total respect to them for braving the elements like that.

      I don’t think the pictures of the workers working on the platform are from the past couple days. There’s no snow on the ground in those pictures so they most likely are relaxing in front of a fireplace. They’re not really braving any elements. Just saying 🤷🏻‍♂️

    It appears the platforms are similar to what was used for the stablelization work.   If only the Contractor could have started the repair upon completion of the stablelization work.  The repair would be done and behind us by now!

    • WSB December 29, 2021 (6:11 pm)

      That’s been addressed by SDOT previously. Among other things, these platforms will be in different areas of the bridge than the center span where the stabilization was focused.

    Seems like what would’ve worked for the Viaduct Would’ve saved us a few billions

    Thank you WSB for your consistent, clarifying,  fact based responses!

    Well the bridge certainly went through the weather tests that were needed, per prior reporting, with the extreme heat and now extreme cold.  2022 will hopefully bring good news about the bridge returning to use and covid going away.

    Even if the Ballard to West Seattle link is elevated or tunneled (I incorrectly assumed it would would share streets as in the clogged mess of south downtown LA, so I’ll accept the egg on the face)  it will not justify the enormous costs and disruptions, a solution that could be easily accomplished with a bus right-of-way, or increased bus service.   If Seattle is anything like LA, then transit options might actually decrease for many bus riders who are funneled – or forced – onto light rail as their bus routes are terminated on the pretext of being redundant.   Bottom line:  I do not think light rail  is going to make a significant difference, in either transit accessibility or traffic congestion, and won’t even keep pace with increasing density – even assuming it attracts a few more who like the idea of riding a train.  But maybe all of this is moot in the future if work pattern change and fewer people commute.

    Weren’t they supposed to have relocated the utilities by the end of December? A little worried they might already be behind schedule…

    When is it supposed to reopen?

Sorry, comment time is over.
