This short truss bridge is just under 70 feet in length and contains five panels. It is however an extremely significant bridge as a very old example of a bridge built by a regionally prolific bridge company, the Pittsburgh Bridge Company. While fewer examples of this company appear to remain in Maryland, Western Pennsylvania has (or had) numerous examples of this company's work. Despite those examples, this bridge is still among the oldest remaining examples of the company.
The nomination for this bridge contains some interesting information. It mentions that records show when this bridge was built, the bridge company was represented by T. M. Nelson Esquire of Chambersburg (Pennsylvania). Later bridges would feature plaques that listed Chambersburg-based Nelson and Buchanan as agents for Pittsburgh Bridge Company. The appearance of T. M. Nelson Esquire with the construction of this bridge is likely an early representation of this company relationship.
Although the overall appearance of the bridge is quite different from the later Pittsburgh Bridge Company Bridges, there is one unique detail that this early example has that was carried on and seen in later examples. The bottom chord and its connections are framed by the floorbeams, which was something distinctive and different that this company did.
The bridge features v-lacing instead of solid plate on top of the end posts and top chord. This is an uncommon feature that few truss bridges display. It changes the way the bridge appears considerably, making it appear even more lightweight and geometrically complex than the normal arrangement with truss bridges, that have the plain plate on top.
The plaques, mounted on the portals, on this bridge are face the opposite direction compared to most bridges, and as such they face the center of the bridge are meant to be read from on the bridge.
Historic integrity is high on this bridge, with no major alterations noted.
