The thudding sound some waterfront residents in Kitsap County noticed was caused by a steel plate at one of the expansion joints on the draw span. While westbound traffic was able to traverse the joint quietly, eastbound vehicles caused the plate to depress slightly and come in contact with the bridge — this contact created the sound. WSDOT adjusted the plates in early 2010, reducing the thudding sound.
