New River Gorge Bridge
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 the world's longest single-span arch bridge for 26 years;[4][5] it is now the fifth longest; the longest outside of China. Part of U.S. Route 19, its construction marked the completion of Corridor L of the Appalachian Development Highway System. An average of 16,200 motor vehicles cross the bridge each day.[1]
The roadway of the New River Gorge Bridge is 876 feet (267 m) above the New River,[5] making the bridge one of the highest vehicular bridges in the world; it is the third highest in the United States. When completed in 1977, it was the world's highest bridge carrying a regular roadway, a title it held until the 2001 opening of the Liuguanghe Bridge in China. Because of its height, the bridge has attracted daredevils since its construction. It is now the centerpiece of the annual "Bridge Day", during which hundreds of people, with appropriate equipment, are permitted to climb on or jump from the bridge. In 2005, the structure gained additional attention when the US Mint issued the West Virginia state quarter with the bridge depicted on one side. In 2013, the bridge was listed on the National Register of Historic Places.
Construction began on the bridge in June 1974, and was completed on October 22, 1977. The bridge was designed by the Michael Baker Company under the direction of Chief Engineer Clarence V. Knudsen and Corporate Bridge Engineer Frank J. Kempf, and executed by U.S. Steel's American Bridge Division. The final cost of construction was $37 million (equivalent to $131 million in 2021 dollars). It was approximately $4 million, or $14 million in 2021 dollars, 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.[6]
At the time, the bridge was the West Virginia Department of Highways' largest project in its history, important both in terms of its overall cost, and that the federal government provided 70 percent of the funding. Construction gave a boost to the state and local economy; completion improved transportation.[7] The bridge cut the vehicle travel time from one side of the gorge to the other from about 45 minutes to 45 seconds.[5][8]
On August 14, 2013, the bridge was listed on the National Register of Historic Places.[3] Even though it was not yet 50 years old, it was listed for its exceptional impact on local transportation and its engineering significance.[7]
The New River Gorge Bridge is within the National Park Service's New River Gorge National Park and Preserve, which protects this portion of the New River Gorge. At the northern end of the bridge, the Park Service operates a visitor center; it has scenic overlooks and a staircase that descends part of the way into the gorge.
