This bridge is a small but attractive structure. Although no plaque remains on the bridge, the bridge is recorded as having been built by the King Bridge Company. The King Bridge Company is regarded as one of the most noteworthy and important bridge companies alongside the other national, prolific bridge companies who were on the iron bridge scene right at the beginning in the 1870s bowstring truss period, producing patents, and contributing their ideas to bridge design and construction of the late 19th century. The Crooked Creek Road Bridge is significant as the end result of that 1870s period of experimentation, an example of the general design of truss that was decided upon to be the most effective for bridge construction, the pin-connected Pratt truss.
This bridge is located near historic Gettysburg. Given the fact that Gettysburg already causes an influx of heritage tourism dollars, preserving this bridge and promoting it as a historic attraction would enhance the heritage experience that visitors to this area can have.
Information and Findings From Pennsylvania's Historic Bridge InventoryDiscussion of Bridge The one span, 68'-long, pin-connected Pratt pony truss bridge built in 1889 is supported on stone abutments. It has built up compression members, eye bar tension members, U-shaped floorbeam hangers, and built up floorbeams. Angle knee braces are placed to the inside of the verticals. Steel stringers and an open steel grid deck were placed in 1972. Plates have been welded to the floorbeams to provide a greater bearing area for the stringers. According to the state bridge card, the bridge was fabricated in 1889 by the King Bridge Co. of Cleveland, a nationally prominent bridge building firm. The bridge is a traditionally composed example of the pin-connected Pratt truss type and design that dominated highway bridge building in the last decades of the 19th century. Once common in the region, they are now increasingly rare with this being one of the two oldest identified examples from 1889 to 1896 in Adams County, and among the oldest pre-1890 pin-connected pony truss highway bridges in the region. The bridge is historically and technologically significant as an example of its type and design by an important fabricator. Discussion of Surrounding Area The bridge carries 1 lane of a 2 lane road over a stream in a rural area of active farms and scattered late 19th to late 20th century houses. There are fields to the southern quadrants and woods to the northern quadrants. The setting does not have the cohesiveness or integrity of a historic district.
