"In 1969 they figured out that Joe Troitino [built] 75% of the stonework on the Blue Ridge Parkway..."
Bridges are an essential element of making the Parkway work as a scenic route for leisurely travel rather than fast paced highway commutes. There are over one hundred bridges which limit access from nearby roads and allow the Blue Ridge Parkway to run nearly uninterrupted over its 469 miles. Some of these bridges are large, complicated overpasses and others are smaller and less involved, like the Pine Creek Bridges. The most famous and most complicated of the Blue Ridge Parkway bridges is the Linn Cove Viaduct. a bridge for carrying a road over a valley It is 1,243 feet long and made up of 153 pieces weighing fifty tons each. While other parts of the Parkway moved earth and rock to lay the road, The Linn Cove Viaduct was built above the land in order to avoid damaging Grandfather Mountain. While the Linn Cove viaduct is made of concrete, most of the bridges and guard walls on the Blue Ridge Parkway were built by Italian and Spanish stone masons. a person whose trade is building with units of various natural or artificial mineral products, as stones, bricks, cinder blocks,or tiles These stone structures, in many cases made with stone from the surrounding areas, are an excellent example of how Parkway planners tried to make all aspects of the Blue Ridge Parkway attractive and natural, even the parts you drive over.
