Amtrak Railroad Bridge
Description
FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The bridge is closed to traffic. It crosses over 2 electrified tracks of Amtrak in a setting with a mix of late 19th to late 20th century residences and businesses in Salunga. A Butler building and modern garage are to the north. Very altered late 19th century vernacular frame residences line the road to the south. The setting does not have the cohesiveness or integrity of a historic district in Salunga. The rail line is the former Pennsylvania RR Main Line, one of the state's most historically significant railroads, established in the late 1840s, and electrified in the late 1930s. The Main Line has been determined eligible by PHMC (DOE 9/14/93).The 3-span, 92'-long metal thru girder bridge built ca. 1898 is supported on ashlar abutments and built-up metal bents with crossbracing. The bent columns rest on stone pedestals. The shallow built-up girders carry built-up floorbeams, timber stringers, and a wood deck with asphalt wearing surface. Metal picket railings are set atop the girders with corrugated sheet metal barriers added over the electrified tracks (ca. 1937). The bridge is a common type/design, developed by the railroads in the mid 19th century, and frequenty applied to overpass bridges from the late 19th to mid 20th century. Although not individually distinguished by its technology, it is historically significant in association with the Philadelphia-Harrisburg division of the PRR's Main Line, one of the most important and heavily engineered railroad right-of-ways in the state. The line was straightened and regraded in the late 1890s and the bridge dates by style and history to that effort. It contributes to the PRR Main Line that has been determined eligible by PHMC (DOE 9/14/93).
