Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 3 span bridge is composed of 2 built up thru girder spans (2 @ 118') built in 1915 and a concrete slab approach span (1 @ 29'), placed in 1975. The thru girder spans have built-up floorbeams with a concrete jack arch deck. A cantilevered sidewalk with a metal railing is placed to the east side. The bridge is supported on a concrete abutment, a concrete bent, and an ashlar pier. The thru girder bridge is an example of a very common bridge type with no individually distinguishing features or details. The bridge's significance is in association with the development of the PHMC-determined eligible PRR Main Line. It dates from the line's period of significance and it is associated with efforts to improve the safety and efficiency of the line by improving grade crossings. The bridge was designed by the railroad's engineering department and fabricated by the Fort Pitt Bridge Works.

Discussion of Surrounding Area

The viaduct carries a 2 lane street and sidewalk over 3 active tracks, a stream, and a local street to the west of Conrail's main yard in the Pittsburgh district. The Conrail line is the former Pennsylvania RR Main Line that has been determined eligible by PHMC (9/14/93). The line is significant for its historic role as an important east-west through route established in the 1850s.
