Madison City Police Officers frequently run traffic radar on Brown’s Ferry from Hughes to County Line. It is most common for them to run radar on Brown’s Ferry in between Wall Triana (Sullivan) and County Line. The speed limit is 35mph, and this is a very reasonable speed where the road is twisty. However there are long straight stretches where traffic can safely and reasonably get up to 50mph on both ends (near County Line and Wall Triana/Sullivan). This is usually where Madison PD Traffic Enforcement Units run their "Moving Radar."
