    Bridge  description is:  metal rivet-connected Pratt Pony Truss, movable double  leaf bascule (fixed trunnion).  Approach spans metal stringer (multi-beam) fixed.  There is one main span and 5 approach spans.  Largest span is 252 feet.  Structure length is 320 feet.  Roadway width is 38 feet.  This bridge was identical to the Monroe Street Bridge  1922) and the Belmont Avenue Bridge (1913).

     This was a difficult project because Franklin and Orleans did no align on both sides of the river and road modifications needed to be made.
