"It was the second in the world to utilize tied-arch technology on a large scale and the first to utilize high-strength silicon steel. It included a stiffening truss concentric with the arch itself, with the floor structure suspended from wire cable hangers which were subjected to pre-tensioning so that the floor structure would not sag under anticipated loads." It took two years to build and cost $3.64m. [B&T]

The West End Bridge spanning the Ohio River at Pittsburgh was designed by George S. Richardson and built by Allegheny County in 1932. The bridge is 1,891 feet [576m] in overall length. From north to south, there are four Warren Pony trusses and the main span that has a 778-foot [237m] tied arch. When it was built, the vertical clearance was 73 feet, and today it is 66 feet. The bridge connects the North Side and the West End neighborhoods of Pittsburgh. This photo was taken in August of 1941. |

Pittsburgh Did What? posted
For a few years in the 1930s, the longest bridge of its kind anywhere on earth was quietly carrying traffic over the Ohio River in Pittsburgh. 🌉 The West End Bridge opened on December 2, 1932, a single sweeping steel arch tying the West End to the North Side. Engineer George Richardson designed it as a tied-arch, a graceful type where the deck itself holds the ends of the arch together like the string on a bow. When it was finished, its 780 foot [238m] span was the longest tied-arch bridge in the world. In a city with more bridges than Venice, it is easy to drive over this one without a second thought. But look up next time you cross it. That great arch was a genuine world record when your great grandparents were young, built by Pittsburgh hands in the teeth of the Great Depression, and it has framed the Point and the meeting of the three rivers for almost a century. Pittsburgh has a way of setting world records and then shrugging them off as just another river crossing. Which of the city's bridges is your favorite to drive across? |

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.

Early morning fog and haze surround the West End Bridge, an impressive steel-through arch that carries US Route 19 over the Ohio River between the West End and North Side in Pittsburgh, Pennsylvania. The atmospheric conditions looked eerie similar to the smog that once enveloped the region, although the air is considerably cleaner today.
