The correct answer to this open question is the following.
We are talking about Blue Ridge Parkway.
Originally called the Appalachian Scenic Highway, work on this North Carolina road began in 1935. In an effort to provide jobs to unemployed in the state, Congress funded workers from the Works Progress Administration, the Emergency Relief Administration, and Civilian Conservation Corps to help with construction. At 469 miles long, the road stretches from the Shenandoah National Park and Great Smoky Mountains National Park.
This is one of the most beautiful highways because of the great natural scenery that surrounds the highway. It has 469 miles from North Carolina to Virginia. It is one of the most visited places by American tourists.
