The Longest Cable-Stayed Bridge of Its Time

When the Arthur Ravenel Jr. Bridge opened on July 16, 2005, it earned the distinction of being the longest cable-stayed bridge in North America and the tallest structure in South Carolina.

A decade later, its 10-year anniversary was celebrated as a symbol of engineering excellence and community pride.

A Replacement Crossing

Grace Memorial and Pearman Bridges

Dear Lykkers! Previously, the Grace Memorial Bridge (constructed in the late 1920s) and the Pearman Bridge (built 40 years later) connected Charleston and Mount Pleasant. However, these bridges became functionally obsolete due to their narrow lanes, limited capacity, and inadequate ship channel clearance.

The Need for a New Bridge

To enhance traffic safety and capacity, the South Carolina Department of Transportation (SCDOT) initiated the ambitious task of designing and building a replacement crossing.

Design and Construction

The Ultimate Solution

The replacement bridge spans 2.5 miles, featuring a 1,546-foot cable-stayed main span. Its design includes eight vehicular lanes, along with pedestrian and bicycle pathways, addressing long-term transportation needs.

Design-Build Method

Given the project’s scope and a five-year completion window, a design-build procurement method was adopted. This approach addressed challenges related to the bridge’s location, size, and inspection requirements.

Key Features

The bridge rises nearly 200 feet above Charleston Harbor’s shipping channel, with twin diamond-shaped towers reaching almost 600 feet. It was designed to withstand seismic events, such as the 1886 Charleston earthquake (magnitude 7.3), and hurricanes, including Hugo.

Post-Construction and Maintenance

Since 2009, the bridge has been under regular inspection and maintenance by HDR | ICA, ensuring its durability and operational efficiency. Maintenance services include bridge tending, mechanical and electrical upkeep, and preservation work.

Award-Winning Design

The Arthur Ravenel Jr. Bridge has received numerous accolades for its size, design, and environmental considerations:

2007

Co-Winner, Best Bridge with Spans Greater than 150 Feet, PCI Design Award (Precast/Prestressed Concrete Institute)

2006

President’s Transportation Award for Environment, American Association of State Highway & Transportation Officials

Grand Award, Engineering Excellence Awards, American Council of Engineering Companies

Excellence in Highway Design, Federal Highway Administration/U.S. Department of Transportation

2005

Outstanding Civil Engineering Achievement Award, American Society of Civil Engineers

Special Award, National Steel Bridge Alliance Prize Bridge Award

A Landmark for Generations

The Arthur Ravenel Jr. Bridge stands as an iconic testament to innovative design, engineering prowess, and community collaboration, enhancing connectivity and safety in Charleston for years to come.
