Mitchell Street Bridge

This structurally and functionally obsolete bridge and its approaches included interfaces with a system of streets, viaducts, retaining walls, sidewalks, public and private utilities, street lighting, railroads, storm drainage and traffic signals. For the replacement, maintaining grade on the approaches was a vital consideration in preserving connectivity with side streets at a reasonable cost. Providing long clear spans over all railroad tracks was a requirement of Norfolk Southern Railroad because this ensured flexibility for future rail tracks. H&L’s solution was based on the design of long span, welded plate girders, tightly spaced to minimize construction depth over the tracks.
