Palm Beach County, Florida Bridges: Spanish River Blvd. Bridges across the Intracoastal Waterway (2)

December 2012 (26.38634 Degrees, -80.07104 Degrees) Spanish River Blvd. Bridges
A closer look at the bascule spans on the Spanish River Boulevard Bridges. I spent some time trying to understand the purpose of the blue box on the right side of the photo. I finally decided it must be a counterweight for the right bascule leaf. As the counterweights rotate downward between the white concrete sides of the piers the bascule leafs are raised into the air.
