The eight lane bridge satisfied the capacity of U.S. Route 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 third longest among cable - stayed bridges in the Western Hemisphere. It was built using the design - build method and was designed by Parsons Brinckerhoff.

Grace Memorial Bridge for former Charleston mayor John P. Grace, who spearheaded the project. The main span of the double cantilever truss bridge was the fifth longest in the world at 1,050 feet ( 320 m ) and soared 150 feet ( 46 m ) above the river. The main span of the second cantilever was the twelfth - longest in the world. The total length of the structure was about 2.7 miles ( 4.3 km ). Following a 17 - month construction at a cost of $6 million, it opened with a 3 - day celebration that attracted visitors from around the globe. Engineers and critics proclaimed colorful descriptions of the unique structure, deeming it `` the first roller - coaster bridge '' and citing that `` steep approaches, stupendous height, extremely narrow width, and a sharp curve at the dip conspire to excite and alarm the motorist. '' Privately owned originally, a $1.00 toll was charged for car and driver to cross. In 1943 the state of South Carolina purchased the bridge, and the tolls were lifted in 1946. By the 1960s the Grace Memorial Bridge had become insufficient, with its two narrow 10 - foot ( 3 m ) lanes built for Ford Model As and its steep grades of up to 6 percent. Later changes to the side rail and curb reduced the lane width further. A new bridge was constructed alongside and parallel to it. Named for the then - South Carolina Highway Commissioner, the Silas N. Pearman Bridge opened in 1966 at cost of $15 million. Its three lanes, at a modern 12 - foot ( 3.7 m ) width, opened to northbound traffic while its older counterpart carried the southbound traffic into downtown Charleston. One lane was reversible on the Pearman bridge, which led to signs warning `` Use lanes with green arrow '' and `` Do not use red X lane '' on the bridge. The two truss bridges had become functionally obsolete by 1979. Extensive metal deterioration caused by the lack of maintenance shortly after Grace Bridge 's tolls were removed limited the capacity of the older Grace bridge to ten ton vehicles ( later five tons ), and the reversible lane on the Pearman was eliminated ( it had been able to switch to three lanes northbound for rush hour traffic ), making that lane southbound permanently, diverting all heavy trucks, buses, and recreational vehicles to that lane on the Pearman bridge. Neither of the bridges had emergency lanes, and the Pearman bridge had no median between the northbound and southbound lanes because of its reversible lane, and it was not until 2002 when flexible barriers were added to the Pearman bridge to prevent head - on collisions. Furthermore, the vertical clearance above the river -- once among the highest in the world -- could no longer accommodate modern shipping vessels. Three of Charleston 's four shipping terminals are situated up the Cooper and Wando Rivers, and the limited bridge clearance excluded the access of ships that would otherwise be beneficial to the economy of South Carolina. Now that the old bridges are disassembled, the world 's largest modern container ships are able to access all terminals of the nation 's fourth - largest container port. Building the bridge Funding Arthur Ravenel, Jr. Raising financial support for a new eight - lane bridge over the Cooper River was a struggle 20 years in the making, prolonged by the state 's insistence that it could not afford such a bridge and by Charleston 's reluctance to provide any funds for the project. Several proposals were made for a toll bridge, but the mayors of Charleston and Mount Pleasant objected. When officials revealed in 1995 that the Grace Bridge scored a 4 out of 100 for safety and integrity, retired U.S. Congressman Arthur Ravenel, Jr. ran for the South Carolina Senate with a goal of solving the funding problem. He helped to establish the S.C. Infrastructure Bank and worked with local, state, and federal officials to create partnerships that helped to materialize the final funding. The State Infrastructure Bank ( SIB ) budgeted $325 million to accompany $96.6 million from the Federal Highway Administration. The project did not become a reality, however, until the SIB agreed to commit to a $215 million federal loan, provided that Charleston County would contribute $3 million a year for 25 years, including an 8.33 % sales tax increase, to the federal loan, as well as yearly payments from the SCDOT and State Ports Authority. The overall price of the bridge totaled around $700 million. Arthur Ravenel Jr. Bridge from Charleston Design Road deck of the Arthur Ravenel, Jr. Bridge. One of the two towers. Charleston 's new bridge over the Cooper River is a cable - stayed suspension design with two diamond - shaped towers, each 575 feet ( 175 m ) high. The total length of the structure is 13,200 feet ( 4.0 km ), with the main span stretching 1,546 feet ( 471 m ) between the towers. 128 individual cables anchored to the inside of the diamond towers suspend the deck 186 feet ( 57 m ) above the river. The roadway consists of eight 12 - foot ( 3.7 m ) lanes, four in each direction as well as a 12 - foot ( 3.7 m ) bicycle and pedestrian path to the design, which runs along the south edge of the bridge overlooking Charleston Harbor and the Atlantic Ocean. The bridge superstructure is designed to withstand shipping accidents and the natural disasters that have plagued Charleston 's history. The span is designed to endure wind gusts in excess of 300 mph ( 480 km / h ), far stronger than those of the worst storm in Charleston 's history, Hurricane Hugo in 1989. Engineers also considered the 1886 earthquake that nearly leveled Charleston. The Ravenel Bridge is designed to withstand an earthquake of approximately 7.4 on the Richter magnitude scale without total failure. To protect the bridge from errant ships, the towers are flanked by one - acre rock islands. Ships will run aground on the islands before colliding with the towers. The bridge includes a shared bicycle - pedestrian path named Wonders ' Way in memory of Garrett Wonders. Wonders was a US Navy ensign stationed in Charleston and was in training for the 2004 Olympics before he died in a bicycle - vehicle collision. The path was included in design of the new bridge because of grassroots efforts by groups such as a fifth grade class at a local elementary school. Construction View from atop the MUSC Parking Garage facing northeast 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 simplifying 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 ( 15 m ) multicolored LED `` beacon, '' but public opinion caused this plan to be scrapped. The fast - paced construction schedule led to contractors to use a self - climbing form system to build the towers. The formwork, supplied by PERI, provided a solution to meet the tight construction tolerances and provide safe access for workers laboring hundreds of feet in the air. The self - climbing system meant that the tower cranes did not have to spend time raising the forms after each segment of concrete hardened, and instead could be better used to haul material from barges below. 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. Fireworks celebration to precede the opening of the new bridge, July 2005 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. Comparison with Talmadge Memorial bridge and Sidney Lanier bridge The proximity and rivalry between Charleston, South Carolina and Savannah and Brunswick often lead to comparisons between the Arthur Ravenel Jr. Bridge, the Sidney Lanier Bridge, and the Talmadge Memorial Bridge, all of which carry US 17. Completed in 2005, the clearance under the Arthur Ravenel Jr. Bridge is actually only 1 foot ( 0.30 m ) taller than both the Sidney Lanier Bridge and the Talmadge Memorial Bridge. Unlike the Sidney Lanier Bridge and the Talmadge Memorial Bridge, however, the Ravenel Bridge has eight travel lanes ; the Talmadge and the Sidney Lanier both have just four lanes. The Ravenel also features a dedicated bike / pedestrian lane. The Talmadge Memorial Bridge also has a similar design as the Alex Fraser Bridge in Vancouver, Canada. As for the span of the three bridges, The Arthur Ravenel Jr. Bridge is 1,546 feet ( 471 m ). The Sidney Lanier Bridge is 1,250 feet ( 380 m ). The Talmadge Memorial Bridge is 1,100 feet ( 340 m ). As for the total length of the three bridges, the Arthur Ravenel Jr. Bridge is 13,200 feet ( 4.0 km ). The Sidney Lanier Bridge is 7,779 feet ( 2,371 m ). The Talmadge Memorial Bridge is 10,032 feet ( 3.058 km ), or 1.9 miles ( 3.1 km ). Bridge run Arthur Ravenel Jr. Bridge view from Patriot 's Point, July 2006. The last fragments of the two old bridges can be seen in the background. The bridge is home to the annual USA Track & Field 10,000 meter ( 6.2 mi ) Cooper River Bridge Run on the first weekend of April. This event attracts up to 50,000 people. The route starts in Mount Pleasant and finishes in downtown Charleston at Marion Square. Media appearances The cover of Darius Rucker 's 2010 album Charleston, SC 1966 features a picture of Rucker, a Charleston native, with the Ravenel Bridge in the background. The 2014 television series Reckless features the bridge in its title sequence. In the video game Need for Speed Undercover a bridge similar to the Ravenel Bridge was featured but only on the PlayStation 3, Xbox and PC versions. It was also featured in the 2012 version of Need for Speed Most Wanted ( but it only crosses half of the water ) The 2009 movie The New Daughter, starring Kevin Costner, features the Ravenel Bridge in several scenes as the movie is based in and around Charleston, South Carolina.
