Lin Cove Viaduct – Blue Ridge Parkway, NC
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.
Linn Cove Viaduct was 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 viaduct itself was the only access road for construction. Each pre-cast section was lowered by a stiff-leg crane and epoxied into position against the preceding segment. Steel cables threaded through the segments secured the entire bridge deck.
