This bridge is a standard plan through truss built to state highway department standards for the period. This bridge also features a number of through plate girder approach spans. This particular bridge is impressive because it utilizes the standard plan that included more v-lacing and lattice on the built-up members, which inadvertently results in a more geometrically complex and visually pleasing structure. This bridge also has a decent gateway function for those entering or leaving Leechburg.
Information and Findings From Pennsylvania's Historic Bridge InventoryDiscussion of Bridge The 5 span bridge consists of a 334'-8" long Parker thru truss main span and 4 simply supported thru girder approach spans ((1 @ 81'-5", 1 @ 80'-7", 1 @ 67'-6", 1 @ 63'-3"). The trusses are traditionally composed with built up members, and while the truss span is long, it has no innovative or distinctive details. It is an example of a bridge type and design that was well established by 1920. Neither the bridge nor its setting are historically or technologically significant. The bridge carries a 2 lane street and 1 sidewalk over the Kiskiminetas River and a Conrail track on the Westmoreland County side at West Leechburg. The railroad was originally developed as the West Pennsylvania RR, a subsidiary of the PRR that was built to take advantage of the coal, coke and burgeoning industries in the county. The line became part of the Pennsylvania's Low-Grade Line that enabled freight traffic to avoid grades on the Main Line, and that gave the PRR an operational advantage. The line is not historically significant. Bridge Considered Historic By Survey: No |
