West End-North Side Bridge, Spanning Ohio River, approximately 1 mile downstream from confluence of Monongahela & Allegheny rivers, Pittsburgh, Allegheny County, PA

description

Summary

Photographs cover approach spans only; Ohio River span not shown.
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.
