SR 99 - SR 509 Southbound Duwamish River Bridge - Bridge Repair - Project map

A map showing the location of the SR 99 southbound Duwamish River Bridge

The SR 99 southbound Duwamish River Bridge has had some settlement due to worn bearings that support the bridge deck. Our bridge maintenance crews will make temporary repairs to these bearings until a contractor can make permanent repairs. The bridge remains safe for travel.
