As Levittown was being built, the steel trussed-arch span of the Pennsylvania Turnpike Bridge over the Delaware River was being erected. The architects, working here for a joint Pennsylvania and New Jersey Turnpike Commission, were successors to Paul P. Cret, whose great Benjamin Franklin Bridge (PH1) was firmly grounded in immense stone abutments. Here they took a more utilitarian course that spans from piers in the river while providing enough height for large ships to pass underneath to such facilities as the Bethlehem Steel's Fairless Plant just to the north. Thousands of high-paying jobs made it a major employer of Levittown residents.
