North of Covington on Highway 51
Leaving Covington city limits the speed limit increases from 45 to 55 after 1 mile the limit goes to 60 after 1.5 miles the limit goes to 65. After 1.5 miles the limit changes to 55. This speed limit reduction is after the city and industry area. The 55 limit stays for around 3.5 miles and the limit again changes to 65 for around 2 miles before changing again to 55 as you approach Ripley, TN. I observe more county and state officers in this 7 to 8 mile stretch of road than any non urban area in the country. Pay close attention or pay traffic school!
