Deck Pratt truss with unusual design involving one end being supported on the bottom chord and the other end being supported on the top chord. Quoting the Railway Age Gazette from May 31, 1912: "The truss span will rest on a pier at the south end, and will be hung from a pin connection in the upper chord at the north end. The erection of this structure will present some interesting problems, for it is desired to erect it as a cantilever from the north end. To do this it will be necessary to construct temporary horizontal and vertical struts under the first panel point of the lower chord and tie the upper chord pins to a very heavy anchorage some distance back from the face of the canyon."
