Two 1950s-era bridges on the Pennsylvania Turnpike/I-476, one over the Lehigh River and one over the adjacent Pohopoco Creek, are being replaced by four new spans by general contractor Walsh Construction Co. with the help of a 600-ton (660 US ton) Manitowoc 18000 lattice boom crawler crane from All Crane of Pennsylvania, a member of the ALL Family of Companies. The huge crane is carefully setting 70 165-foot precast concrete bridge beams for the Pohopoco spans on piers more than 100 feet above the creek.
