Bridge Documentation

This late example of a cantilever truss bridge is noted for its span length and significant roadway width. It was the third largest cantilever span in the United States when completed. The bridge has deck truss approach spans as well, which were noted to include a pin and hanger detail indicating the deck truss spans also function as a cantilever truss. Note that the total length and span numbers given refer only to the through truss and the deck truss spans, and do not include the expansive ramp approach systems at each end of the bridge. The overall length of bridge including approaches is about 14,150 feet.
