This historic bridge was demolished and replaced in 2009!

Featuring steel fabricated by Phoenix, this was an impressive and rare example of a pin-connected truss bridge with the Pennsylvania truss configuration. The bridge had atypical sway bracing and portal bracing design, which gave the bridge a slightly unusual appearance. V-lacing and lattice present on the bridge's built-up beams added to the intricate beauty of the complex Pennsylvania truss configuration. This bridge had been closed to traffic, in 2009 it was demolished and replaced with an ugly modern bridge. This was a foolish decision for New Castle, who could have instead restored this bridge so it could have continued to be an attractive feature of the city that would have also been functional. New Castle should have ignored the non-historic finding of the Historic Bridge Inventory which was far outdated by the time the bridge was replaced. This bridge, with pinned connections and rivets utilized many technologies that are no longer used today. The bridge was also more attractive than a modern bridge replacement could ever hope to be as is evidenced by its replacement shown in the photo below.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The one-span, 245'-long and 46' wide, pin-connected, steel Pennsylvania thru truss built in 1914 is supported on stone abutments. The trusses are traditionally composed. All of the members are built up except for the eye bar tension diagonals. The built up floorbeams are framed into the verticals below the lower chords. The sidewalk is supported on built up brackets and is finished with a plain metal railing. The bridge is long, but it is a later and average span length of a pinned connected truss with subdivided panels. Earlier examples include 11 3022 0010 0000, the Johnstown Inclined Plane bridge built in 1890. This example is not historically or technologically significant.

Discussion of Surrounding Area

The bridge carries the street over a river in New Castle in a mixed use area of cleared land, 1920s warehouses, and a late-19th, early-20th century residential area and modern houses. The setting does not appear to have the cohesiveness or significance to be a historic district.

Bridge Considered Historic By Survey: No
