Steel truss bridge construction appears to have been all the rage in King County during the early 1930's. The county even devotes a full exhibit in their archives to these bridges. Why were so many built during this period? A need to replace existing wooden structures? New roads needing bridges? Surplus steel availability? Advances in truss design and construction technology? New Deal economic stimulus programs? Whatever the impetus, it's fun to see them when they were brand spanking new.
Following are a few bridges close to home. All photos courtesy King County Archives.
