SDOT: High bridge repair: moving forward on final phase of epoxy crack injection and carbon-fiber wrapping; maintenance work continues
Information from Seattle Department of Transportation
The final phase of epoxy crack injection and carbon-fiber wrapping is underway on the West Seattle Bridge. We’re using the same methods from before the new post-tensioning system was completed: strengthening and reinforcing sections of the bridge’s concrete by filling existing cracks with an epoxy compound and applying sheets of polymer-infused carbon-fiber. Along with the compression forces from the post-tensioning system, these repair methods work to prevent the concrete from cracking in the future.
Crews continue to make progress on major maintenance work needed to prepare the bridge to reopen to traffic. This week, we put up more signs on the recently installed overhead sign structures and began installing covers on the newly replaced expansion joints. We also continued pouring concrete for the new bridge deck overlay on the Fauntleroy Expressway just west of the high bridge and finished pouring the replacement concrete panels on the bridge’s western approach.
