This bridge is one of two attractive stone arches on this road. While the Historic Bridge Inventory appears to have at first evaluated the bridge as not historic, the Historic Bridge Inventory records finally show the bridge was listed historic in 1988. The two bridges are significant in their own right as historically intact multi-span examples of their type, but they are also noteworthy for being two historic bridges on a single relatively short stretch of roadway.
A. Calhoun was the engineer for this bridge and Thomas McAdams was the contractor.
As of 2010, while PennDOT's overall historic bridge preservation commitment, particularly with metal truss bridges, is perhaps the poorest in the entire country, some credit is deserved for their choosing to rehabilitate a number of beautiful historic stone arch bridges in eastern Pennsylvania. It is hoped that PennDOT will see the feasibility and value of preserving these stone arch bridges and extend the commitment to a larger pool of stone arch bridges, as well as other historic bridge types such as concrete arch bridges and metal truss bridges.
The Swamp Creek Road Bridges have been selected for preservation and rehabilitation by PennDOT. Transystems (owner of former company Lichtenstein, a firm with noted historic bridge rehabilitation experience) has been selected to design the rehabilitation projects. Credit is given to Transystems for the plans that the drawing on this page was adapted from, and the details of the rehabilitation as outlined by Transystems is shown below.
The
Information and Findings From Pennsylvania's Historic Bridge InventoryDiscussion of Bridge The 3 span, 100'-long stone closed spandrel arch bridge, built in 1892, has fieldstone-capped stone parapets. A portion of the spandrel wall has been rebuilt in kind, and concrete aprons protect some of the arch footings. The bridge was recently repointed. A large crack is visible on the upstream side of the intrados of the central span. Discussion of Surrounding Area The single lane bridge carries a 2 lane road over a stream in a sparsely developed, forested setting near a mill complex and Camp Sumney. Bridge Considered Historic By Survey: No Information and Findings From Pennsylvania's Stone Arch Bridge Management PlanDiscussion of Bridge This bridge is recommended for long-term preservation. The bridge ranks in the top third of all stone arch bridges under study in this plan. Structural problems, including cracks and loose stones in the superstructure and advanced scour in the substructure, are to be addressed by PennDOT, which should raise the condition code. The bridge is very narrow, but it handles its low volume of traffic adequately and little additional growth is anticipated in the area. The waterway is adequate. This National Register of Historic Places-listed bridge is located in a greenway, resulting in a very high cultural values code. The bridge has also received public support (two questionnaires, three emails, and one petition). The bridge has historic integrity. Ratings The Marlborough, Swamp Creek Road Bridge is owned by
PennDOT and is ranked 21st. Recommendation: Recommended for long-term preservation. |
