All the concrete deck segments are now in place on North America's longest cable-stayed bridge, the Cooper River Bridge in South Carolina. Onlookers applauded Friday’s completion of the 471m main span, which is flanked by distinctive diamond-shaped towers. The bridge's design and build joint venture is Palmetto Bridge Constructors, made up of Tidewater Skanska and Flatiron Constructors, with Parsons Brinckerhoff Quade & Douglas providing design services. The US$632 million bridge is due to open this summer.
