Client: South Carolina Department of Transportation

Parsons Brinckerhoff Role: Design

Arthur Ravenel Jr. Bridge
Parsons Brinckerhoff served as lead design firm to the joint venture team that constructed the $531 million, cable-stayed Arthur Ravenel Jr. Bridge over the Cooper River. Replacing two obsolete Cooper River bridges, the bridge has a main span of 1,545 feet (470 meters)—the longest cable-stayed span in the Western Hemisphere. In addition to eight traffic lanes, the bridge features a pedestrian walkway/bikeway providing a magnificent view of the surrounding area. The project also included two extensive roadway interchanges connecting historic Charleston to the town of Mount Pleasant. The structure features two visually striking diamond-shaped concrete towers that are protected from ship collision by large rock islands. The towers are 573 feet (175 meters) high from water line to their tops. Approximately 8,000-foot-long (2,440-meter-long) high-level approach spans utilize composite steel girders and reinforced concrete piers. The structure was also designed for hurricane wind forces. The entire main line structure includes the main cable-stayed structure and approaches totaling approximately 13,200 feet (4,000 meters). The bridge opened to traffic on July 16, 2005, one year ahead of schedule. Among its many awards, the bridge received the 2006 Federal Highway Administration Excellence in Highway Design Award, citing that “Its innovative structure engineering solutions were matched by an emphasis on environmental stewardship, including special protection of the habitats of loggerhead sea turtles.”

Bridges are more than passages over water; they are landmarks in their own right that support the flow of people and goods.  Bridges touch people every day, providing critical access channels as well as visual context.  Communities and owners typically require structures whose appearance enhances the surrounding area while reducing congestion and promoting neighborhood revitalization.

For more than 125 years, Parsons Brinckerhoff has worked on thousands of structures that have become hallmarks of the communities they serve.  Our staff is well versed in steel and concrete bridges, including cable-stayed, arch, truss, segmental, suspension, girder, movable and floating, as well as multi-level highway interchanges.  For highways, railroads, transit systems and pedestrians, our bridge services range from feasibility studies and environmental permitting through preliminary and final design, to program and construction management.  We also provide inspection, rating, seismic analysis, rehabilitation design, and value engineering services.

Balancing technically challenging designs with complex site considerations, Parsons Brinckerhoff projects have won numerous prestigious awards for engineering excellence.  As a measure of our efforts, we are proud to have been selected as the Top Bridge Design Firm (#1) for 2010 in a recent survey of government clients by Roads and Bridges magazine.

Parsons Brinckerhoff’s bridge assignments range in size and scope from simple studies and assessments to complex multibillion-dollar multidisciplinary efforts involving landmark structures.  No matter how big or small the job, Parsons Brinckerhoff is committed to maximizing infrastructure resources and responding to today's needs with cost-effective, aesthetic solutions.
