The Wichert truss, designed by E. M. Wichert of Pittsburg, PA, in 1930, is a cantilever spandrel-braced deck arch that is not a "true arch" bridge. The curved lower chord gives the bridge the form of an arch, but it does not rely on arch action to carry the load. The open diamond panel above each pier is the easily recognised mark of this truss type; without a vertical truss member in this hinged location.
