Description 

This Bridge was built in 2004 along the old alignment of the Rutland Railroads Islands Line, which has been converted into a multi-use pedestrian path. The original bridge at this location was a 3 span structure lost in the Great Flood of 1927. It was replaced in 1928 by a 2 span structure that served until the lines abandonment in the early 60's. In 1972 the span was scrapped, but the piers remained. When the line was converted to a path, a small bike ferry operated at this location to connect the two sections. Rehabilitating the old piers, this new bridge was fabricated and placed on top of them, with the 2 through spans accounting for the original spans, and a approach span being added on the south side

Michael,

As its a modern truss, I'm not sure it really matters but, I don't think we can justify calling it a Pratt through truss. Stylistically, its a bowstring but I doubt it functions as a true bowstring from the old days.

That said, its nice to see the crossing complete and something bowstring-like used.

Regards,

Art S.
