This road is properly known as Sportman Road, but many maps show it as Sportsman Road (with an s).

This bridge is a traditional example of a pin-connected truss bridge. Overall, the truss itself retains fair historic integrity. Some alterations exist. Welded repairs can be found, such as at the eyebar hears. Also, the portal knee braces have been removed. The function of the bridge is altered by the addition of a steel arch that supports all live loads (traffic) on the bridge. The truss only supports itself, and does not help carry traffic in any way. This type of retrofit is one of many ways in which historic truss bridges can be preserved, and like all preservation options, it has pros and cons. The pros are that the arch can carry greater loads than the pin-connected truss bridge. Cons are a substantial alteration to the visual appearance of the bridge since it is hard to ignore the huge arch rib going through the truss web. Another con is because the truss no longer carries a live load, the owner of the bridge has lost one of the incentives to maintain and repair the truss. The bridge can be allowed to deteriorate to a greater extent than it could carrying traffic, which can make rehabilitation of the truss more challenging.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The single span, 85'-long, tied arch bridge was erected in 1994 around a 1901, traditionally composed, pin connected, Pratt thru truss bridge. The arch is supported by skewbacks anchored to the vertical faces of the original abutments. Suspended steel rod hangers pick up rolled section floorbeams that support steel stringers and a timber deck. The trusses bridge is not tied to the arch. It supports only its own weight.

Discussion of Surrounding Area

The bridge carries 1 lane of a road over a stream in a rural area of active farms and scattered 20th century houses that does not have historic district potential.
