Design visual of improved highway and new Davis Slough bridge
Plans are in the works to raise and widen SR 532 and replace the Davis Slough bridge. WSDOT engineers are designing the improvements now and expect to start construction in summer 2014. The highway will be raised 5 to 9 feet and the shoulders, lanes and median will all be widened between Smith and Eide roads, west of the new Camano Gateway Bridge.
The current bridge was built in 1949. We will replace the 2-lane, 32-foot wide bridge over Davis Slough with a new 56-foot wide bridge. The new bridge will be 9 feet taller, provide one 12-foot lane in each direction, a 4-foot median, and shared 14-foot shoulders to accommodate bicyclists and pedestrians and allow room for vehicle breakdowns. The highway on either side of the bridge will be raised approximately 5 feet in order to raise the roadway above potential flood and storm influences.
We had this design visual on display at a community open house in August 2012. The open house was an opportunity to review plans and pictures for the project, as well as talk with engineers.
