History
The section between SR 17 and US 11/64 was originally numbered as SR 2A around 1934. This route was renumbered to SR 317 during the 1983 Tennessee state highway renumbering.In between Chattanooga and Collegedale SR 317 formerly went along Old Lee Highway to Apison Pike. It has been since rerouted with the completion of the Volkswagen Drive exit on I-75. It now joins I-75 at exit 7 and runs concurrently with I-75 to exit 9, where SR 317 turns along Volkswagen Drive to Apison Pike.
The Tennessee Department of Transportation is working to widen and improve the Apison Pike section of SR 317, located between I-75 and SR 320 in four separate phases. Phase 1 consisted of constructing a new five-lane road between I-75 and Old Lee Highway, part of the relocated section of SR 317. Phase 2, which took place between January 2015 and September 13, 2017, widened the segment between Old Lee Highway and SR 321 from two to five lanes at a cost of $24.2 million. Phase 3, which began on March 13, 2020, and is expected to be completed by June 2025, is the most complex and expensive phase, at a cost of $93.1 million. It involves widening the route from two to five lanes between SR 321 and Layton Lane and will consist of an entirely new alignment in some places. Phase 4, the final phase, will widen SR 317 between Layton Lane and SR 320.
