I-76 Allegheny River Bridge
Owner: Pennsylvania Turnpike Commission
Design / Construction Engineering and Inspection: FIGG
The I-76 Allegheny River Bridge replaced an aging steel structure with a new, long span concrete bridge. The twin 2,350’ long structures were built on an alignment parallel to the existing turnpike and feature 532’ main spans over the Allegheny River. It is the first cast-in-place concrete segmental bridge in Pennsylvania. Aesthetic features were developed in an Owners’ charette. The design was inspired by the site’s landscape and includes a variable depth superstructure and a stone pattern on the twin wall piers.
Including the 2011 Globe Award from the American Road & Transportation Builders Association
