America's Covered Bridges. Ronald G. Knapp

locals take great pride in the three surviving covered bridges at Forksville, Hillsgrove, and Sonestown even as others are only recalled in memory and faded photographs. (Sullivan County Historical Society’s Museum)

      Spine The Schofield Ford or Twining Ford Bridge, which was originally completed in early 1874 in Bucks County, Pennsylvania (page 205), was burned by arsonists in 1991 and completely rebuilt in 1997 by local volunteers. Today, it offers passage across the picturesque Neshaminy Creek in Tyler State Park. A stone pier supports the bridge, which likely was constructed as a single span utilizing the Town lattice truss.

       Front endpaper The longest historical covered bridge in the United States, the Cornish-Windsor Bridge (page 172), crosses the Connecticut River between New Hampshire and Vermont. On a heavily traveled route with a ten-ton load limit, the bridge carries two-way traffic day and night. In addition to ongoing maintenance to its Town lattice truss, extensive repairs have been carried out periodically since it was constructed in 1866. (A. Chester Ong, 2010)

       Back endpaper Thomas Wilson’s painting of Eagle Mills in Rennsselaer County, New York, depicting the village around 1845, places a two-lane covered bridge at its center, flanked by large mill- or factory-type structures along with a wooden mill building next to the dam. Today, a cider mill sits next to the dam and an undersized covered two-lane pedestrian bridge crosses Poesten Kill nearby. The main part of the village is seen in the distance.
