Description 

This is an impressive span built by the Boston & Maine railroad to cross both the Saint Lawrence & Atlantic Railroad, NH16, and the Androscoggin River. The main span is a dual (side by side) pin connected Pratt deck truss, with trestle approaches on both sides. On the western side part of the trestle approach was replaced by a long deck plate girder to accommodate New Hampshire route 16.

The Deck is currently in use as the Presidential Recreation Rail Trail. A small walkway has been added through the truss for the Appalachian Mountain Club trail
