This very unusual bridge uses a spandrel braced design that is normally only found in steel arch bridges. The bridge also includes several approach spans supported by tower-style bents that also resemble a braced design usually reserved for steel construction. These facts make for a unusually complex and intricate looking concrete bridge. Unfortunately the bridge is buried amongst many trees and viewing the bridge is exceedingly difficult.
