Waterford Covered Bridge
The Waterford Covered Bridge is a Town lattice truss covered bridge spanning LeBoeuf Creek in Waterford Township, Erie County in the U.S. state of Pennsylvania. The bridge was built in 1875, and is in length. The Waterford Covered Bridge is one of two remaining covered bridges in Erie County, along with the Harrington Covered Bridge. The bridge is also the only Town lattice truss bridge in the county and one of only 19 in Pennsylvania. It was documented by the Historic American Buildings Survey in 1936 and was listed on the National Register of Historic Places in 1980. In 2011, the bridge was closed due to its deteriorating condition.
== Design ==
The Waterford Covered Bridge is situated southeast of the borough of Waterford in Waterford Township. The bridge spans the over LeBoeuf Creek, and has an overall length of . It is wide and carries a single lane of Niemeyer Road (Township Road 463). The road deck itself is wide, and is made up of "transverse decking" and a pair of , linear runners to reduce the noise from loose boards and to guide automobiles. The bridge only has clearance of , which has played a role in repeated collisions by oversized vehicles.
The bridge was designed by Richard Cross using a Town lattice truss. The truss consists of a lattice of beams crossing at 45 to 60-degree angles and connected by wooden pins. There are only nineteen bridges remaining in Pennsylvania using the Town lattice, and the Waterford Covered Bridge is only one in Erie County. It is the also the only covered bridge in the county to have been painted, with the exterior of the bridge painted barn red. The bridge also has "an unusual, blue, metal pipe structure" attached to the abutments on the bridge's south side. The structure is supported with a king post framework and, presumably, connects to nearby pipelines.
Originally, a white sign was mounted above each portal that declared "Old Kissing Bridge built in 1875 by the Phelps Bros." Sometime in the mid-2000s, the sign was taken down. When the bridge was closed, large "Bridge Closed" signs were mounted in the same location with concrete barricades placed across the road on the bridge's approaches.
