The first bridge of its type in the United States, the Linn Cove Viaduct is a product of design and construction techniques developed in Europe. The S-shaped structure contains 153 concrete segments, only one of which is straight. Weighing 50 tons each and joined by epoxy and massive steel tendons, the segments form a deck nearly one-quarter mile long that is supported by seven piers.

Computer technology enabled engineers to design and construct this geometrically complex structure. The technique used in building the viaduct allowed the rugged terrain and the forest of this ancient mountain to be preserved. Conventional construction methods would have obliterated Linn Cove's massive boulder field and severely altered the steep mountain profile.

Erected by National Park Service, U.S. Department of the Interior.

2. Marker detail: Linn Cove Viaduct construction

The viaduct was constructed "from the top down." Starting from the south end, a crane lowered each segment into place. Once a segment was secured, the crane then moved over the completed section to add the next segment. Pier components were lowered into place from the bridge deck.

1. History of the Linn Cove Viaduct. As the last piece of the Parkway to be completed, the Linn Cove Viaduct was a peak of Parkway engineering and environmental protection. Completed in 1983 at a cost of almost $10 million, the Linn Cove Viaduct is 1,243 feet long and contains 153 segments weighing 50 tons each. The American Society of Civil Engineers designated it a National Civil Engineering Landmark. (Submitted on May 23, 2019, by Cosmos Mariner of Cape Canaveral, Florida.)

. This seven-mile section of the Blue Ridge Parkway – once the Parkway’s missing link – was completed in 1987. It was delayed for twenty years as environmentalists, adjacent landowners, engineers, and architects sought a design that would preserve and protect the fragile habitat of adjacent Grandfather Mountain.
