PHOTO ESSAY ABOVE: Linn Cove Viaduct (MP 304). The stunning and elegantly designed, 1,234-foot Linn Cove Viaduct was completed in 1987 as the final piece of the Blue Ridge Parkway. The structure was built with 153 precast concrete segments that were assembled without any breakage. RIGHT: North Carolina State Line (MP 216.9). The shape of a state, the general design of parkway signage and the pretty turns of a road that was " painted with a comet's tail, " reflect well the timeless beauty of the 469-mile roadway connecting the Shenandoah and Great Smoky Mountains national parks. 38 BLUERIDGECOUNTRY.COMhttp://www.BLUERIDGECOUNTRY.COM
