Covell, Chief Engineer of the Allegheny County Department of Public Works. Its main span is a steel two-hinged through arch measuring 750 feet, stiffened by a Pratt truss. The approach spans combine two-hinged deck arches, Warren deck trusses, a crescent arch truss, and a 75-foot girder span. The overall length is about 5,510 feet, carried on sixteen piers, and the granite piers and steel railings are noted in the survey. The bridge's main span is regarded as a very fine example of the two-hinged metal through arch, and its design is compared with the Hell Gate Bridge in New York. The nomination treats it as an important engineering work, and it is one of two examples of its bridge type included in the group. The bridge carries vehicular traffic and is recorded as unaltered.","period_of_significance":"1930-1932","architect_builder":"V.R.
