The Hares Hill Road Bridge superstructure consists of one 103 feet 4 inches (31.50 m) wrought-iron lattice girder span.

The bridge has been extensively rehabilitated several times, one of which added the current open grid steel deck.

The structure carries one lane of traffic on Hares Hill Road (unsigned State Route 1045) across French Creek.

The original superstructure consisted of the two wrought-iron arched girders with lattice webbing and a timber floor system.

In 2009, the Pennsylvania Department of Transportation (PennDOT) was programmed to spend $1.7 million to rehabilitate this bridge and improve its load capacity without interfering with its historical nature.

PennDOT's contractor worked to rehabilitate the wrought iron through truss bridge by reconstructing damaged and deteriorated wingwalls; reconstructing stone masonry parapets with reinforced concrete; and installing powder-coated brown guiderail to protect the blunt ends of the parapets.
