Built in 1934 by TVA as an important part of TVA's first hydroelectric dam project, Norris Freeway connected the railroad in Coal Creek in Anderson County to Halls Crossroads in North Knox County. It was built to transfer materials to the dam and provide access to administrative offices in Knoxville, and was considered the world's first limited access road built for utilitarian or construction project purposes. The freeway runs 21 miles, cost 41.4 million to build, and had billboards and commercial uses along it limited by TVA to provide a scenic drive to Norris Dam and Norris.
