Built in 1918, this bridge is a relatively late example of a stone arch bridge. Engineer Nathan R. Rambo held on to traditional methods of bridge construction, particularly stone, when other engineers had moved on to steel and concrete. This bridge is of decent length, and is also fairly tall, making it an impressive example of its type.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 4-span stone arch bridge with stone parapets was listed in the National Register in 1988. The intrados has been pargetted. The bridge was built in 1918 under the direction of Chester County Engineer Nathan R. Rambo to replace an iron truss bridge from 1870. In 1993, a 30'-long section of the parapet was repointed and new coping added. There has been no significant change in the bridge's status since the previous survey.

Discussion of Surrounding Area

The bridge is in the village of Rock Run, north of Coatesville.

Bridge Considered Historic By Survey: Yes

Information and Findings From Pennsylvania's Stone Arch Bridge Management Plan

Discussion of Bridge

This bridge is a strong candidate for long-term preservation. It ranks in the top third of stone arch bridges under study in this plan. Historic elements are largely intact, making it relatively inexpensive to rehabilitate. Its waterway adequacy borders on very high. Built in an area of low development potential and possessing a relatively wide deck, the bridge should be able to handle its traffic for some time. The bridge is listed in the National Register of Historic Places, and has a high values code; it is locally and regionally significant. This bridge has received public support (one letter, two emails, two telephone calls, and one meeting at which this bridge was a focus). However, the bridge also has some problems that need to be monitored. Its condition code is very low due to extensive scour. In addition, the footings of at least two piers are exposed, making additional scour possible. The bridge's sight distances at the approaches are also subpar. However, these problems can be corrected using the procedures of the Maintenance Manual developed for this project.

Ratings

The Valley, Wagontown Road Bridge is owned by PennDOT and is ranked 33rd.
Condition Code = 40 - low
Transportation Code = 54 - moderate
Waterway Adequacy Code = 59 " high
Cost to Rehabilitate or Replace Code = 56 - high
Anticipated Development Code = 58 - high
Recreational, Historical, and Cultural Values Code = 54 - moderate
Public Input Code = 54 " moderate

Recommendation: Recommended for long-term preservation.
