What is a switchback road?

A switchback road is a type of mountain road or trail that has a series of sharp turns or hairpin bends. The purpose of the switchbacks is to make it possible to ascend or descend a steep hill or mountain slope. The road or trail may zigzag forwards and backwards, and switchback turns often have sweeping views of the surrounding landscape.

Switchback roads are often seen in rugged terrain, where building a straight or gently curving road is not feasible. They are commonly used in mountainous areas, where steep ascents and descents must be navigated to travel from one area to another. The tight turns and steep grades of switchback roads require skillful driving and can be perilous for motorists who are not accustomed to driving in these conditions.

Switchback roads have been used for centuries, and many historic switchback trails still exist today. While some switchback roads are narrow, rocky paths designed for foot or pack animal traffic, others are well-developed routes that are suitable for modern vehicles. The most famous examples of switchback roads include the Pacific Coast Highway in California, the Gotthard Pass in Switzerland, and the Stelvio Pass in Italy.
