They close it to normal traffic for periods af time for ( let's say agressive driving).There are stories and pictures like the couple with this very large boat in tow on their way to Florida and took this road by mistake and burnt out their trucks transmission and almost crapped their pants.its called The Dragons Tail and the address is
