View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge is an attractive, traditional example of a riveted Warren through truss. It has received some alterations, and modern bolts are visible on portions of the bridge. Otherwise, historic integrity is good. However, structural integrity is apparently not so good. This bridge had a very low 2% sufficiency rating in 2006, and the bridge is on a state-owned route. However, the bridge is listed as being maintained by the railroad. Regardless of who owns the bridge, PennDOT will likely do what it normally does and see the bridge demolished, whether by their hand or the railroad's. On-site conditions and time did not allow for an inspection under the bridge's deck, which is apparently where the problems are, because the trusses as seen from the road appear to be in decent shape.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The single span, 148'-long and 19' wide, 6 panel, riveted Warren thru truss with verticals bridge is supported on concrete abutments. The trusses are traditionally composed, and repairs to the lower chords have been done with in kind material bolted to the original fabric. An example of common period technology, the bridge is not individually significant, and the rail line that it crosses is not historically significant. Neither the bridge nor its setting are historically or technologically significant.

Discussion of Surrounding Area

The bridge carries a 2 lane road over CSXT railroad tracks in a rural area of active farms. A third track has been removed. The line is the B&O RR's former Somerset & Cambria RR, a branch line connecting Johnstown with the B&O's Pennsylvania main line. The branch line is not historically significant.

Bridge Considered Historic By Survey: No
