SDOT: High bridge repair: more work on post-tensioning; continuing bridge maintenance
Information from Seattle Department of Transportation
This week, we poured concrete for one of the bridge’s replacement overhead sign structures, which hold the directional signage you see when driving on the bridge. As maintenance work continues, we will replace eight more of these sign structures on the bridge.
We made more progress on post-tensioning preparation and other elements of the repair work such as additional exterior epoxy crack injection and carbon-fiber wrapping. Epoxy injections and carbon-fiber work will continue both before and after the bridge is post-tensioned.
We also began the process of replacing the concrete surface on sections of the Fauntleroy Expressway, which is the structure to the west of the high bridge that connects it to Fauntleroy Way. This work involves grinding away a half inch of the bridge’s deck in preparation for new concrete in the future. We want to ensure that the roadway surface is ready for traffic when the bridge reopens.
