Significance: After two decades of agitation by the local business community, the West End-North Side Bridge was completed in 1932 by the American Bridge Company under contract to Allegheny County. The main span is a graceful, 778-foot long, tied-arch structure which employed pre-stressed hangers between the twin arches and the bottom chords. This bridge was placed on the National Register of Historic Places in 1979 for the engineering and aesthetic qualities of the main span. Approaches to the high level main span are by three pony trusses on the south and four pony trusses on the north.
Project Information: This recordation was conducted for the Federal Highway Administration and the Pennsylvania Department of Transportation in July and August 1985, to fulfill the requirements of the Memorandum of Agreement (MOA). The MOA stipulates that the northern approach spans, the focus of this study, be recorded prior to their demolition and the construction of the West End Bridge Ohio River Boulevard Interchange.
