Town Line Bridge

Town Line Bridge

Town Line Bridge is an endangered Lenticular through truss over the Otselic River on Town Line Road in Cortland County, New York. It is 13 extant examples of its type remaining in the state.

The Town Line Bridge was constructed in 1888 by the Berlin Iron Bridge Company of East Berlin, Connecticut. 1 A pony truss was added to the east side to cross over a sawmill’s spillway by the Groton Bridge Company in 1903. The spillway was later reclaimed by nature and gradually filled in. The western abutment was later faced with concrete and the deck was last replaced in 1976. 1

Because of the structure’s deteriorating condition, the Town Line Bridge was closed to automobile traffic in 1990, although it remains open to pedestrians and snowmobiles. 1
