Hares Hill Road Bridge, Spanning French Creek, Kimberton, Chester County, PA

Significance: The Hares Hill Road Bridge, probably best described as an arched girder with latticed webbing is the only known surviving example of Thomas W. H. Moseley's "Wrought Iron Lattice Girder Bridge" and closely resembles his patent of August 30, 1870 (No. 106,855). Though modified substantially since its initial construction, it remains an excellent visual example of the proprietary vernacular designs that competed in the market for small highway bridges during the years immediately following the American Civil War. The Hares Hill Road Bridge, together with three others by Moseley, were the first iron bridges built in Chester County. Collectively, they represent that community's first experiment with this "new" bridge type as an alternative to timber and stone masonry for bridge construction. The Hares Hill Road Bridge was one of only two identified as a "bowstring arch-truss" in an inventory of state-owned highway bridges conducted in 1982-1985 by the Pennsylvania Department of Transportation and the Pennsylvania Historical and Museum Commission. It is the only iron highway bridge surviving in Chester County that is still in public use.
