State Route 396 (SR 396), commonly referred to as Saturn Parkway, is a 4.47-mile-long (7.19 km) east–west primary state route located in the city of Spring Hill in the U.S. state of Tennessee. The entire route is a controlled-access highway, and provides direct access between the General Motors Spring Hill Manufacturing plant and Interstate 65, as well as the business district of Spring Hill. It takes its name from Saturn Corporation, a subsidiary of General Motors that operated the plant from 1990 to 2007 as its sole manufacturing facility.
