This is the only Fink truss in the entire Commonwealth of Pennsylvania. The Fink truss was one of the most popular truss designed used in the first iron railroad bridges built in the United States. They most commonly were deck trusses, but came in through truss format as well. The Fink truss's use quickly died out and extant examples were also rapid demolished when increased railroad loads rendered these early bridges highly insufficient and obsolete. Only a few examples remain nationwide today.
The interpretive signage next to the bridge states incorrectly regarding the Fink truss: "It is still the most widely used truss design in bridge building today." It is unclear where this statement came from since nothing could be further from the truth. The Fink truss quickly died out by the 1880s when the Pratt truss and later the Warren truss became the dominant truss configurations.
This bridge today sits preserved in a park setting as a non-functional exhibit. The history and original use of the bridge is unusual since it was built to essentially widen a stone arch bridge in Phoenixville, with the trusses supporting a sidewalk. One truss line was added alongside each of the three spans of the stone arch. When the bridge was relocated here, two of the truss spans were placed parallel to each other to form a more traditional independent two-truss structure. It is not known what happened to the third truss line.

Discussion of Bridge
According to Chester County records, the bridge was built in 1991. The 2 span prestressed concrete box beam bridge replaced a stone arch bridge constructed in 1847. Two Fink deck trusses were added to the stone arch bridge in 1870 to support a sidewalk. The rare Fink trusses were relocated to a pedestrian trail in Warwick Park, Warwick Twp., Chester County in 1991. The box beam bridge is in the Phoenixville Historic District, and due to its date of construction is a noncontributing structure.
