State Route 40
State Route 40 (SR 40) runs as a secret, or hidden designation for US 64/US 74 from downtown Cleveland, in Bradley County to the North Carolina state line near Ducktown, in Polk County. SR 40 was also a former designation for part of APD-40, which is the origin of part of the common name of that route. State Route 40 becomes secondary east of its intersection with SR 60 in Cleveland.
