The Arthur Ravenel Jr. Bridge, South Carolina, USA

The Arthur Ravenel Jr. Bridge, also known as the Cooper River Bridge, is a cable-stayed bridge over the Cooper River in South Carolina, connecting downtown Charleston to Mount Pleasant. The eight lane bridge satisfied the capacity of U.S. Highway 17 when it opened in 2005 to replace two obsolete cantilever truss bridges. The bridge has a main span of 1,546 feet (471 m), the longest among cable-stayed bridges in the Western Hemisphere. It was built using the design-build method and was designed by Parsons Brinckerhoff.

Groundbreaking on the bridge occurred in 2001 in Mount Pleasant. The bridge was built as a design-build project, meaning that one contract was signed to both design and construct the bridge. This meant that construction could begin even while the design was not yet finalized. The bridge was built by a joint venture of two major construction firms operating under the name Palmetto Bridge Constructors. The joint venture partners were Tidewater Skanska of Norfolk, Virginia and Flatiron Constructors of Longmont, Colorado. The construction joint venture hired Parsons Brinckerhoff to complete the design. For the sake of simplifiying labor and equipment resources, Palmetto Bridge Constructors actually managed the building of the bridge as five separate projects (the two highway interchanges at either end of the bridge, the two approach spans, and the cable-stayed span) going on simultaneously.

By the summer of 2002 the foundations for the towers and most of the piers were in place and the rock islands were completed. The steel and concrete towers began to ascend from the islands soon after. Originally, each of the towers was to be topped with a 50 foot multicolored LED "beacon," but public opinion caused this plan to be scrapped.

The first cables were hung from the towers in 2004--as a time-saving measure, this was done before the towers were wholly completed. Sections of the deck were built outward from each of the towers as more cables were hung.

The decks of the approaches were taking shape as well. Construction of part of the roadway actually occurred over the top of the old cantilever bridges, which remained open to traffic without interruption.

A ceremony was held in March 2005, when the last slab of the deck was added, thus making the bridge "complete." But paving, installation of lights and signs, and cleanup meant that the bridge would not open for another four months.

Following a week-long celebration that included a public bridge walk, concerts, dinners, and fireworks, the bridge was dedicated and opened on July 16, 2005 – one year ahead of schedule and under budget. The bridge was featured on the TV show Extreme Engineering.
