Swinomish Channel Bridge
Photo taken by Douglas Butler in January 2018
BH Photo #415486
I believe that this bridge was built in 1927, not 1937. The county highway from Mount Vernon to Anacortes was added to the state highway system as the Anacortes Branch of Primary State Highway 1 in 1937. The enclosed WSDOT photo shows this bridge circa 1938.
