Last week, we continued assembling the work platforms that we’ll use as an elevated workspace to complete epoxy injections and carbon-fiber wrapping on the outside of the bridge. We expect to lift the first platform into place this Saturday on the west side of the Duwamish Waterway. 

In the coming weeks, we plan to begin core drilling on the inside of the bridge at Pier 16. This will create access holes for post-tensioning cables that reinforce the strength of the bridge’s concrete to run through. We’ll also be relocating existing utility lines at this location to make room for the additional post-tensioning cables.  

Work platforms for the West Seattle High-Rise Bridge (high bridge) under construction beneath the Spokane Street Swing Bridge (low bridge). This platform will be moved and hoisted into place Saturday, January 8.

Rigging hangs from the high bridge. The work platforms will be attached to these steel cables, which will support the weight of the platforms as we complete epoxy injections and carbon fiber wrapping.

Heads up that in coming weeks there may be some traffic impacts on SW Manning St and E Klickitat Ave while we raise the other set of work platforms on the east side of the bridge. Stay tuned for more details about timing in next Friday’s update.
