This weekend, we'll begin pouring structural concrete on the bridge. We completed the final core drills through the bridge’s pier structures this week, which is a major milestone to be ready for future post-tensioning. The next step is to finish installing forms for blocks and anchors that will secure the post-tensioned cables. We’re planning the first structural concrete pour for the post-tensioning system on Saturday.  

We’ll continue to keep you informed as concrete pours progress, moving us closer to post-tensioning the bridge for added strength, followed by a final round of epoxy injections and carbon-fiber wrapping, and then testing and preparing the bridge to reopen. 

As we continue our maintenance work on the West Seattle Bridge, we poured concrete for more expansion joints this week. We also made more progress in our carbon-fiber wrapping of the bridge’s exterior as we moved to the east span work platforms and began applying sheets of carbon-fiber to the concrete girders.
