The construction of the new Allegheny River Bridge for the Pennsylvania Turnpike Commission near Pittsburgh, Pennsylvania has made significant progress. With a 532' main span over the Allegheny River, this will be Pennsylvania’s first long span concrete segmental bridge. Construction of the twin 2,350' structures began in May 2007 and is scheduled for completion in 2010 to accommodate major golf tournaments at the nearby Oakmont Country Club (Fig. 11).
