State Route 397, also known as the Mack Hatcher Memorial Parkway, is a primary state route that serves as the perimeter road for the city of Franklin, Tennessee.

Route description[edit]

State Route 397 begins south of Franklin on U.S. Route 31 / State Route 6 (Columbia Avenue) and continues around the east side of the city to U.S. Route 431 / State Route 106 (Hillsboro Road).[1] It is a two-lane arterial class road with right-of-way varying from 250 to 300 feet (91 m).[2]


On December 2, 2005, TDOT (Tennessee Department of Transportation) announced that the preferred alignment for the Mack Hatcher Parkway Western Extension would be Alternate G. This route, 7.5 miles (12.1 km) long, begins at U.S. Route 31 / State Route 6 south of Franklin (the Columbia Highway) and ends at U.S. Route 431 / State Route 106 north of Franklin (Hillsboro Road). It will go around the west side of Franklin. The Western Extension will create a complete perimeter around Franklin, divert through traffic from the city, and provide easy access to other nearby routes.[2]
