SDOT presented updates at the West Seattle Bridge Community Task Force on Wednesday, November 10th. The repair remains on track for completion by mid-2022.
The negotiations for the Maximum Allowable Construction Contract (MACC) for the West Seattle Bridge repair are complete, and SDOT expects to issue the formal Notice to Proceed for the project next week.
While most of the repair work will take place inside the bridge, upcoming visible work on the outside will include creating lifting points for the external work platforms with “hydroblasting”; work crews and trailers, and other equipment will be on the bridge deck soon as Kramer crews return to the bridge. When the work platforms (similar to those used last year for the bridge emergency stabilization) are being installed, there will need to be short term night/weekend closures of the lower bridge.
Post tensioning work and epoxy injections in cracks will begin in December; additional details on schedule information should be available soon.
SDOT notes the schedule is “risk-loaded.” This means it accounts for consideration of risks, such as weather (e.g. snow), supply chain disruption, worker shortages and other issues. After completion of the repair, SDOT will test the bridge for strength of the bridge before reopening to traffic. They estimate it will take no more than two weeks but said during the meeting that they expect it to be shorter.
A month before opening to traffic, SDOT will share the reopening date and activities they plan to commemorate the opening. They noted the activities will not delay opening the bridge to traffic.
