Abstract: Authorized by Congress in 1944, the Foothills National Parkway partly traverses the foothills of the Great Smoky Mountains in Eastern Tennessee. Large sections of the parkway cross high ridges located parallel to the Tennessee boundary of Great Smoky Mountains National Park. The parkway is best known for its unobstructed views of the Great Smokies to the south and the Tennessee Valley to the north. Unfortunately, construction of the Foothills Parkway has been plagued by a lack of funding over a period of several years. Even though right-of-way along the parkway’s entire 71-mile route was acquired years ago, sections were not completed until just recently.
