Description 

Typical of truss bridges at river crossings c. 1907, particularly as constructed by the New York, New Haven and Hartford Railroad in its upgrading o the then 40 year old line. Unlike similar bridges, on the line, however, this one includes the remains of the earlier (c. 1870) bridge abutments. These stand inside the 1907 abutments.
