State Route 76 (Missouri)
Located in southwest Missouri between U.S. Route 60 and U.S. Route 63 at Willow Springs and the Oklahoma state line near Tiff City, State Road 76 is 200 miles of ups and downs. Since the road runs through the Missouri Ozarks, it is very hilly. And, while it does have some hairpin turns, it mostly consists of big sweepers, so you can build up quite a head of steam. The scenery is also spectacular. Much of the time you are driving under a canopy of oak and maple trees, which means the road can be treacherous in late fall. Head here in summer and hit the gas.
