No the names are not typos on my part, although it is possible the Historic Bridge Inventory made an error. The official name was spelled "Keys", while the road name is "Keyes Road".
This is a very small pony truss with riveted connections, having only four panels. This bridge has lattice guardrails, unlike the other Nelson and Buchanan bridges in the county that have v-laced railings. The bridge sits on concrete abutments, which for Pennsylvania, is more unusual, since most bridges are on stone abutments. Although listed as a Pratt truss by the historic bridge inventory, you could call this a double-intersection Warren, since the diagonals are all the same size. It is as much a Howe as it is a Pratt, in my opinion. The various truss configurations sometimes run together when the truss bridges get short.
Information and Findings From Pennsylvania's Historic Bridge InventoryDiscussion of Bridge The single-span, 61'-long and 15' wide, riveted Pratt pony truss bridge built in 1903 is supported on concrete abutments. The trusses are traditionally composed, and the floor beams are located above the lower chords. Although the bridge appears to be complete, it is located in a county and region noted for its numerous complete truss bridges, and it is not historically or technologically significant. It is similar to other bridges in the county from the same period that were fabricated by Nelson & Buchanan. Discussion of Surrounding Area The bridge carries one lane of a two-lane road over a stream in a sparsely developed, wooded setting. Bridge Considered Historic By Survey: No |
