Lane reductions on SR 99 near the West Seattle Bridge for Spokane Street Overcrossing Project
Contractor crews for the Washington State Department of Transportation recently began work to bring down and replace an elevated section of State Route 99 just south of the West Seattle Bridge. The bridge was built as a temporary structure back in 1959 and needs to be replaced. When they finish, they’ll leave Seattle’s SODO neighborhood with a stronger concrete bridge better equipped to withstand the test of time.
In late February, crews shifted traffic to the west side of the overpass and began work to demolish and rebuild the east side. Crews will demolish and rebuild one side of the bridge at a time to keep traffic moving at reduced speed in both directions until the work is complete. Traffic will get through the work zone, which spans SR 99 between South Nevada Street and an area just south of the West Seattle Bridge, in one southbound lane and two northbound lanes. Occasional weekend closures of all lanes will be necessary. The $9.2 million construction project is scheduled to be complete in June 2014.
Construction progress tools, including traffic and detour maps, and project contact information are available on the SR 99 Spokane Street Overcrossing webpage, or go to www.wsdot.wa.gov and search “SR 99 timber bridge”.
