Scope Of Work
This project features twin 2,350’ cast-in-place concrete segmental bridges carrying The Pennsylvania Turnpike over the Allegheny River, Allegheny Valley Railroad, Norfolk Southern Railroad, and Freeport Road.

The six-span structures have piers ranging in height from 57’ to 102’ which include aesthetic rockwork features inspired by the local landscape, over 8,000,000 pounds of reinforcing steel, 1300 LF of drilled shafts, nearly 50,000 CY of concrete, and over 3,000,000 pounds of post-tensioning.
