The study area consists of five corridors with potential accommodations for improved transit service between Clarksville and Nashville, including:
- The existing Interstate 24 highway corridor, linking Clarksville and downtown Nashville with regional and national connections via the National Highway System (NHS);
- The existing State Route 12 (Ashland City Highway) highway corridor, connecting downtown Clarksville and downtown Nashville via Ashland City;
- The existing CSX Transportation and R. J. Corman Railroad Group railway corridor, connecting downtown Clarksville and downtown Nashville via Goodlettsville, Ridgetop, Springfield, Adams, and Guthrie, Kentucky; Note: Due to the volume of current and projected freight traffic along the CSX corridor, accommodating passenger AND freight traffic on the CSX/RJ Corman rail line is not feasible for current RTA NWCTS purposes. The corridor also has reduced utility due to out of direction travel, going from Nashville to Guthrie, KY and on to Clarksville.Because of these two issues, the CSX/RJ Corman Corridor was eliminated from further consideration.
- The Nashville and Western railway corridor, currently operated in part by the Cheatham County Railway Authority (CCRA) between Nashville and Ashland City with former right-of-way (ROW) and partially remaining infrastructure between Clarksville and Ashland City; and
- The existing State Route 112 (US Route 41 Alternate) highway corridor, running roughly parallel to and southwest of Interstate 24 and linking downtown Clarksville and downtown Nashville via Pleasant View with regional and national connections via the NHS.
