Featured Bridge - New River Bridge
On June 28,
1973, the West Virginia
Department of Highways awarded a bridge contract that set new world
records. Recently commemorated on the West Virginia quarter design,
the bridge is the state’s crown jewel.
The New River Bridge was
constructed by the American Bridge Division of US Steel at a cost of
nearly thirty seven million dollars and opened to traffic in
1977. At the time, the bridge was the most expensive single project
ever undertaken by the Appalachian Development Highway program.
It carries the state’s Appalachian
Corridor L highway or US 19 across the massive New River gorge deep
in the hills of Fayette County.
With a main span of seventeen hundred
feet, the steel arch bridge was the world-record-holder for
twenty-five years until 2003, when it was topped by another steel
arch bridge in Shanghai, China.
The total length of the bridge and
approaches is just over three thousand feet. It is supported by
nine land piers and two abutments.
Contributing to the massiveness of the
span are over twenty-one thousand tons of structural steel,
seventeen hundred tons of reinforcing steel, seventeen thousand
cubic yards of concrete for the substructure and six thousand cubic
yards of superstructure concrete, making a total weight of more than
eighty-eight million pounds.
During construction, rail lines at the
bottom of the gorge on either side of the river transported
machinery and materials to the site. A thirty-five hundred-foot
cableway across the canyon erected the steel, the largest piece of
which weighed one hundred seventy-two thousand pounds.
At eight hundred seventy six feet
above the waters of the New River, the New River Bridge is the
second-highest in the nation and the highest east of the
Mississippi.
It would top the Washington Monument
by three hundred twenty five feet, making it the perfect site for
BASE jumpers on the only day such parachuting is legal—Bridge Day,
the third Saturday in October.
West Virginia has some of the
country’s most exciting and innovative bridges, which are setting
the standard for bridge design worldwide.
The Mountain State continues to lead
the way in bridge aesthetics, innovations, and safety while looking
forward with confidence to future crossings. |
