Close

State Route 455, the Tennessee Waltz Parkway, is a short bypass around Ashland City in Cheatham County. The general routing is southeast–northwest. SR 455 is less than 2 miles (3.2 km) in length. The route is a continuation of a bypass from State Route 12 to State Route 49 which runs by the A.O. Smith water heater factory to a point just north of the Cumberland River bridge which was not originally designated a state route, but came under state maintenance when SR 455 was created. State Route 455 has its origins in a 1997 referendum in which the voters of Ashland City authorized a 1/2 cent sales tax increase with proceeds going to build and maintain a continuation of the bypass back around to Route 12. The road was finally completed in 2005.
