Lewiston, ID

Old Spiral Highway is said to be one of the best motorcycle roads in the US state of Idaho. The very twisty road (64 curves) is short, is curvy, is smooth, and is most definitely sweet.

Originally constructed in 1917, this historic road, also known as the Old Lewiston Grade, takes 64 turns to traverse 2000 feet of elevation change. It was considered a huge feat in engineering and a breakthrough at the time. The road was the subject of the 1950s rock n' roll song called "Hot Rod Lincoln".
