You might recall that SDOT has closed the eastbound Spokane Street Viaduct -that’s the continuation of the West Seattle Bridge east of Highway 99 – a few times this year for pothole repair. Before the first closure, we reported on SDOT’s big-picture plans, pursuing grant funding for more-extensive repair. Today, the city announced that grant has been secured – one of three city bridges to each get at least $4.5 million “from the Federal Highway Administration Bridge Improvement Program, which is funded in part by the Bipartisan Infrastructure Law and then passed to WSDOT‘s Local Bridge Program,” and on down to the city from there. The announcement said only that the Spokane Street Viaduct’s $5 million grant would be used for “repairs to the existing deck,” so we asked SDOT for a few more details about what would be done and when. Spokesperson Mariam Ali‘s reply:
The federal funding is to support the replacement of the overlay for the south half of the bridge that carries the eastbound lanes of traffic. The existing concrete deck overlay exhibits significant signs of “alligator skin” cracking and damage. The project will replace the existing overlay and fix any concrete deck distress. We are currently in the design phase for this project and have not yet determined the construction timeline, which would likely occur in the next few years.
The eastbound (south) side of the SSV is its older section – the westbound (north) side includes what was built a decade ago. The other two city bridges getting federal grants announced today are the Jose Rizal Bridge to Beacon Hill ($5 million for paint) and the 15th/Leary bridge in Ballard ($4.5 million for earthquake safety).
