View The Wichert Truss Patent

This bridge is an extremely long bridge that is noted for the rare Wichert truss design. This modification of the traditional continuous/cantilever design is noted for an unusual design above the piers of the bridge, where the truss has a special shape that was designed to mitigate some of the problems that were involved with the design of continuous truss bridges in the first half of the 20th Century. The trusses on a Wichert take the shape of a rhombus over each pier.

Take a look at this page to learn more about this bridge and the Wichert design.
