The South Newfane Bridge is a historic bridge, carrying Parish Hill Road across the Rock River in the village of South Newfane, Vermont.

It is a Pratt through truss span, manufactured from rolled I-beams in 1939 to replace a bridge washed away in flooding.

It was listed on the National Register of Historic Places in 1992.

The trusses are built primarily out of steel I-beams, which have been fastened together using bolts.

The use of I-beams in its construction marked an evolution in bridge construction after the state's devastating 1927 floods: the I-beams were less expensive, but added weight to the structure over earlier materials.
