New River Gorge Bridge is located in West Virginia

The New River Gorge Bridge is a steel arch bridge 3,030 feet (924 m) long over the New River Gorge near Fayetteville, West Virginia, in the Appalachian Mountains of the eastern United States. With an arch 1,700 feet (518 m) long, the New River Gorge Bridge was for many years the world's longest arch bridge;[2][3] it is now the third longest.[4] Part of U.S. Route 19, its construction marked the completion of Corridor L of the Appalachian Development Highway System. The bridge is crossed by an average of 16,200 motor vehicles per day.[1]

The roadway of the New River Gorge Bridge is 876 feet (267 m) above the New River,[3] making it the fifth highest vehicular[5] bridge in the world, and the third highest in the Americas (behind the Mike O'Callaghan – Pat Tillman Memorial Bridge over the Colorado River between Arizona and Nevada, bypassing the Hoover Dam) and the Royal Gorge Bridge. When it opened in 1977, the New River Gorge Bridge was the highest vehicular bridge in the world, a record it kept until the 2004 opening of the Millau Viaduct in France. Several suspension bridges in China have since surpassed both of these bridges in height, with the current record holder being the Si Du River Bridge which opened in November 2009, with 1,549 feet (472 m) of clearance above the Si Du River.

In 2005, the structure was further immortalized when a depiction of the span was placed on the West Virginia state quarter.

History

The old U.S. 19 bridge over the New River, over 800 ft (244 m) below the canyon rim.

Construction began on the bridge in June 1974, and completed on October 22, 1977. It was designed by the Michael Baker Company, under the direction of Chief Engineer Clarence V. Knudsen, and executed by U.S. Steel's American Bridge Division. Final cost of construction was $37 million (approximately $4 million over bid). It is made from COR-TEN steel. The use of COR-TEN in construction presented several challenges; notable among them was ensuring that the weld-points weathered at the same rate as the rest of the steel.[citation needed]

Completion of the bridge cut the travel time from one side of the gorge to the other from about 45 minutes to 45 seconds.[3][6]

Tourism

View of the New River Gorge Bridge from the National Park Service Overlook

The New River Gorge Bridge is within the National Park Service's New River Gorge National River, which protects this portion of the New River Gorge. At the northern end of the bridge, the Park Service operates a visitor center with scenic overlooks and a staircase that descends part of the way into the gorge.

A steel catwalk two feet (60 cm) wide runs the full length of the bridge underneath the roadway. Originally built to facilitate inspections, the catwalk is open for guided, handicapped-accessible quarter-mile "Bridge Walk" tours using safety rigging.[3][7][8]

The bridge is the centerpiece of Fayette County's "Bridge Day", held the third Saturday of every October.[3] This festival includes demonstrations of rappelling, ascending, and BASE jumping,[9] Bungee jumping, however, has been banned during Bridge Day since 1993. The bridge is closed to vehicular traffic during the festival; until recently,[when?] two of the bridge's four lanes were open to traffic during the festivals, but security concerns have now prompted the closing of the entire span to vehicles during these events.[citation needed]

The first person to jump off the New River Gorge Bridge was Burton Ervin, who lives in Cowen, West Virginia, and was a coal-mine foreman. Burton jumped on Friday, August 1, 1979, using a conventional North American Aerodynamics Mini Rig System with a 32-foot Lopo canopy. Four BASE jumpers have died at the bridge, three of these during Bridge Day festivals,[10][11][12] and one other killed while performing an illegal jump.[citation needed]
