The Waterford Covered Bridge is an 86-foot (26 m) Town lattice truss covered bridge crossing LeBoeuf Creek in Waterford Township, Erie County in the U.S. state of Pennsylvania. It was built in 1875 and was listed on the National Register of Historic Places on September 17, 1980.[1] The bridge was documented by the Historic American Buildings Survey in 1936.

It is the only Town lattice truss bridge in Erie County[1] and one of only nineteen in Pennsylvania. The bridge structure's sufficiency rating on the Federal Highway Administration National Bridge Inventory was only 18.4 percent and its condition was deemed "basically intolerable requiring high priority of replacement."

Overview

The Waterford Covered Bridge is located in Waterford Township, just east of the borough of Waterford. The bridge is located 0.7 miles (1.1 km) from Waterford on Niemeyer Road (Township Road 463), which intersects Water Street in Waterford 0.3 miles (0.5 km) off of U.S. Route 19. The bridge crosses the LeBoeuf Creek, a tributary of French Creek.

The bridge was designed by Richard Cross using a Town lattice truss.[3] The Town lattice truss was patented by Ithiel Town in 1832 and was used to make bridges with small, light pieces instead large, heavy pieces that were more expensive to make. They are only nineteen Town lattice truss bridges remaining in Pennsylvania and the Waterford Covered Bridge is only one in Erie County.[4] The bridge also has "an unusual, blue, metal pipe structure" on the exterior of the bridge's south side supported with a king post framework.[1]

History

The Waterford Covered Bridge was built in 1875 by the brothers Charles and James Phelps. A sign that was mounted on the gable of one of portals of the bridge said, "Old Kissing Bridge built in 1875 the Phelps Bros."[1] The sign has since been taken down.

In 2001, Waterford Township was given a $54,000 grant by the Pennsylvania Historical and Museum Commission (PHMC) to replace the rafters, roofing, and shake shingles on the bridge.

Modern use and status

The bridge was damaged twice when oversized trucks have attempted to cross it. The first incident occurred on June 17, 2003 when a Ford F-450 box truck attempted to cross the bridge. The second incident occurred on December 9, 2005 involving a FedEx truck that was 8 inches (200 mm) taller than the bridge's 10-foot (3.0 m) clearance and 3,580 pounds (1,620 kg) over the bridge's posted 3 ton load limit.[5] Several of the bridge's deck planks, support beams, and cross pieces were damaged, although the bridge's integrity was not compromised and was never closed to traffic.[5]

Evans' 2001 Pennsylvania's covered bridges: a complete guide described the bridge as being "in fairly poor condition."[1] The Federal Highway Administration National Bridge Inventory found the sufficiency rating[a] of the bridge structure to be only 18.4 percent.[2] It found that the bridge's foundations were determined "to be stable for assessed scour conditions," and that the railing "does not meet currently acceptable standards".[2] Its overall condition was deemed "basically intolerable requiring high priority of corrective action", with an estimated cost to improve the bridge of $750,000.[2]

Bridge dimensions

The following table is a comparison of published measurements of length, width and load recorded in different sources using different methods, as well as the name or names cited. NBI measures bridge length between the "backwalls of abutments" or pavement grooves and the roadway width as "the most restrictive minimum distance between curbs or rails". The NRHP form was prepared by the Pennsylvania Historical and Museum Commission, which surveyed county engineers, historical and covered bridge societies, and others for all the covered bridges in the commonwealth. The Evans visited every covered bridge in Pennsylvania in 2001 and measured each bridge's length (portal to portal) and width (at the portal) for their book. The article uses primarily the NBI and NRHP data, as they are national programs.

Notes

a. ^ The National Highway Administration established the sufficiency rating, which can vary from a low of 0 to a high of 100, as a way to prioritize federal funding for bridges. The rating is calculated based on "structural adequacy, whether the bridge is functionally obsolete, and level of service provided to the public".[6] Federal funds are available for replacement of bridges with a rating of 50 or below, while those with a rating of 80 or below qualify for rehabilitation.[7] In 2007, Pennsylvania had 22,291 bridges over 20 feet (6.1 m) long, of which 42.9 percent were either structurally deficient or functionally obsolete.[8]
