The Elm Street Bridge (Neshanic Station Bridge) over the South Branch of the Raritan River, is a rare example of a lenticular, or parabolic, truss. The structure consists of two spans and is 285 feet in length. It was built in 1896 by the nationally known Berlin Iron Bridge Company of East Berlin, Connecticut. The Elm Street Bridge still retains its historical integrity and original design, and is the best preserved example of this type of truss bridge in the state. It was rehabilitated in 2007 by Somerset County.
