Every Day is a Winding Road
There are parts of Route 66 where the road is straight as an arrow. Conversely, there are parts of Route 66 that wind and twist. You’ll see both on Route 66.
Oatman, Arizona is an example of one twisty, dangerous, stretch of road. Several locations along Route 66 leading up to Oatman have cars that have gone over the side. It’s part of the attraction of Route 66.

Route 66 Leading Up to Oatman
Yet, the road leading up to Oatman from the west side is long and straight until you hit the base of the mountain. (By the way, note in the above photo the condition of the road. Let me remind you, much of Route 66 is maintained by local businesses and people.)
