ABSTRACT: When completed, the Foothills Parkway (Parkway) in east Tennessee will skirt the northern boundary of the Great Smoky Mountains National Park, offering panoramic views of America's most visited park. At a proposed length of approximately 72 miles, to date only 22 miles are open to the public, approximately 6 miles on the east end and approximately 17 miles on the west end. Another 16 miles of the Parkway is expected to open in 2017 between Wears Valley and Wallnd, TN. All but 1.6 miles of this section of the Parkway were constructed in the 1980's. The last 4,000 feet of the Missing Link are currently under construction. Five bridges are needed to traverse the rugged terrain. Foundations for these bridges bear directly on rock or micropiles bonded into rock. This paper will provide some history of the Parkway, the site and construction conditions, and the micropile foundations needed to support closing the Missing Link.
