Bridge Rehabilitation, Replacement and Seismic Retrofit

Revised January 2011

Due to age and extensive use, some of Seattle’s most heavily travelled bridges are deteriorating and in need of significant repair. Other bridges are in need of seismic upgrades in order to make the bridge less vulnerable to earthquakes. To help meet the needs of our most vulnerable bridges, the Seattle Department of Transportation is leading a program to rehabilitate, replace and/or seismically retrofit multiple bridges across the city.

The Bridge Rehabilitation, Replacement and Seismic Retrofit Program is funded in large part by Bridging the Gap, a $365 million voter-approved levy for transportation maintenance and improvements.
