FOLLOWUP: Repairs about to start for hole in West Seattle Bridge ramp to northbound Highway 99

12:06 PM: During the West Seattle Bridge Community Task Force‘s February meeting (WSB coverage here), we got first word of a plan to repair a hole in the pavement on the ramp to northbound Highway 99 (which has remained accessible via eastbound Spokane Street). The ramp is a state structure, not a city structure, so we asked WSDOT for details, but at the time they had few. Now they do. The ramp is scheduled to close next Monday (April 18th) for about two weeks, explained by WSDOT as follows:

We are going to break up and remove the concrete around the hole all the way through to the girders underneath the surface to expose the rebar. The rebar strengthens the concrete under the tension of vehicles driving over it. Once we chip the concrete, we will repair the rebar and then pour concrete to fill the void where the hole in the deck used to be. That process will take about a week. To finish, we’ll need an additional week while the ramp remains closed for the concrete to cure. We need dry weather in order for the concrete to cure properly so the schedule may change depending on the weather.

So far, next week’s weather looks rainy.

3:30 PM: As commenters pointed out, this will affect Metro buses. There were no reroute advisories when we published this, but after we inquired with Metro, an advisory went out – see it here. Rerouting, but no missed stops, Metro says.

    This would impact multiple downtown bound bus routes and push them off 99, correct?

      55, 56, 57, C Line, 21 & more (?)

        Also the 120 and 125

          It is yet another example of over weight buses tearing up the infrastructure. Any bus that goes up 99 can go up 4th and in to town with. very  little issues  

          • CAM April 16, 2022 (1:26 am)

            Sure. There’s no other heavy vehicles that use that route. Just buses. Everything is the fault of people who ride public transit and we should get them out of the way of the poor people sitting in their private vehicles who are put upon to have to deal with those transit users issues.

      A PLAN ?!?  To FIX A HOLE ?!?  Wow……..

      • bill April 16, 2022 (9:27 pm)

        Do you want it fixed correctly?

  • John April 15, 2022 (12:25 pm)

    So at least 2 weeks of bus detours through SoDo I’m guessing?

    A WEEK?? to do THIS work?!?

    A private concrete finish company could do this project in a day with 3 workers.

    Concrete dries in a week?? No no…. not even close. Concrete is durable after 24 hours and cures in about 28 days. AND there are rapid setting products that might be even quicker!

    C’mon man!! WSDOT – do better

    • Bus April 15, 2022 (3:36 pm)

      Rapid-setting products don’t have the same load ratings as slower-curing versions of the same product.  There’s always a tradeoff for speed.  There have been tunnel and bridge collapses due to contractors using the speed set products when the slow cure was specced.  It’s a terrible idea.  Please just let the road engineers do their jobs.

    • A local April 15, 2022 (4:54 pm)

      Eh, theres that saying about doing it quick, cheap, or properly. But you cant have all 3.Sure, residential quick set cement dries in 24 hours, but this isnt your patio where a few people, pets and yard objects are all the weight it has to take. The stuff used on roads has to take a lot more weight, and it has to last a longer. Its not the same thing as the stuff you see at home depot.Quit being so angry and outraged too. It doesnt solve anything and makes you look silly when youre mad about something you dont understand.

        The ad for “armchair civil engineer” obviously did not attract a surplus of qualified candidates.

    • 935 April 15, 2022 (8:45 pm)

      Armchair engineer huh? Patios? naw….here’s an example. Simple search for “Rapid Strength Concrete” Location is California – but it jives. I’m pretty sure WSDOT did it for panel replacement as well.

      Happy Easter weekend everyone!!

  • Jeepney April 15, 2022 (4:10 pm)

    Nice to get this taken care of before the bridge opens in less than 2 months (my prediction).

    • East Coast Cynic April 15, 2022 (7:39 pm)

      August, and I hope I’m wrong and that it’s earlier.

  • Mj April 15, 2022 (5:29 pm)

    Jeepney – ditto 

  • Wseattleite April 15, 2022 (5:49 pm)

    We can be comforted that at least it is not a SDOT project, and take six times as long. 

  • brandon April 18, 2022 (11:28 am)

    Now to be closed for two weeks??

Sorry, comment time is over.
