State Route 306 (SR 306) is a secondary state route in Bradley and Meigs counties in Tennessee.
SR 306 begins at an intersection with SR 60 in the unincorporated community of Hopewell a few miles northwest of Cleveland in Bradley County. The route continues north as Eureka Road through mostly farmland for several miles. Several miles later the route passes through the Chickamauga Lake Wildlife Management Area before coming to an intersection with the western terminus of SR 308 (Lower River Road). To continue on SR 306, northbound motorists must stop and make a left turn at this intersection; the southbound lane of SR 306 contains a stop sign at this intersection. Continuing as Lower River Road and running south of the Chickamauga Lake embayment of the Hiwassee River, SR 308 travels more westerly, and a few miles later crosses into Meigs County, becoming Brittsville Road. A few miles later, SR 306 reaches its northern terminus with SR 58 in the unincorporated community of Brittsville.[2]
