A ribbon-cutting dedication ceremony on September 11,heralded the completion of the Parkway and the end, too, of a narrow and crooked mile detour around Grandfather Mountain via the Tonahlossee Trail U. Most other parkway viaducts are steel girder structures supported by reinforced concrete or steel piers.
The only trees cut were those directly beneath the superstructure. Steel cables threaded through the segments secured the entire bridge deck. The Linn Cove Viaduct is one of the most complicated concrete bridges ever built.
Kristina Plaas photo As the last piece of the Parkway to be completed, the Linn Cove Viaduct was a peak of Parkway engineering and environmental protection.
Contact the Park Mailing Address: Out of total segments, only one – the southernmost – is straight. The final section is not only a carolin of engineering and sensitivity to the environment; it is a joy to drive, safe but thrilling.
This steel girder structure is supported by arched stone piers and stone-faced abutments, and is the only viaduct to feature this treatment. National Park Service landscape architects and Federal Highway Administration engineers agreed the road should be elevated, or bridged, where possible to eliminate massive compufer and fills.
Engineers were faced with a serious question: History of the Linn Cove Viaduct. In the meantime, other portions lnn the “missing link,” most of them north of the Viaduct, were completed bit-by-bit between and As the last piece of viaduch Parkway to be completed, the Linn Cove Viaduct was a peak of Parkway engineering and environmental protection.
Moore negotiated a compromise location. This method eliminated the need for a “pioneer road” and heavy equipment on the ground.
History of the Linn Cove Viaduct
Viaducts are elevated roadway sections carrying the road high above dry ravines or across the shoulders of mountains where extensive and aesthetically unpleasing fill sections would otherwise be required. In addition to 12 bridges, the 7. Visit the Linn Cove Viaduct Milepost to experience this engineering feat in person.

Figg and Muller Engineers, Inc. Each pre-cast section was lowered by a stiff-leg crane and epoxied into position against the preceding segment. The earliest of these is the Rocky Mountain Viaduct, constructed inon the northern section of the parkway at milepost How do you build a road at an elevation of 4, feet without damaging one of the world’s oldest mountains?
The only construction that occurred at ground level was the drilling of foundations for the seven permanent piers, on which lynnn Viaduct rests. Computer control kept Linn Cove Viaduct construction measurements accurate to 0. The Linn Cove Viaduct is 1, feet long and is made up of segments weighing 50 tons each.
A key factor in this controversy was environmental concern over Grandfather Mountain.
The viaduct was constructed from the top down to minimize disturbance to the natural environment.
