This is a 4 lane highway with a center turn lane. The speed limit is 30 mph. There is always a state trooper at the bottom of a long slope. You have to ride your brake constantly to keep your speed down. He always has a car pulled over. Traffic isn’t very heavy for the type road. It is almost impossible to keep your car under 30mph. The entire city of Johnson City, TN is a speed trap. For example,the city annexed a 10 Fort strip along interstates that run into other cities & counties just so they could write tickets. Unbelievable, I know, but just look at a city limit map of this town & you’ll see what I mean.
