Many people ask why not build it straight up to save costs
Why Not Build Roads Straight Up Mountains?
Building straight roads up mountains may seem like a cost-saving measure, but safety and practicality must come first. Steep inclines make driving dangerous, particularly for heavy vehicles. Straight roads would be difficult for vehicles to navigate, leading to increased fuel use, engine wear, and accidents. Zigzag roads, or switchbacks, reduce the gradient, making the ascent gradual and safer for vehicles of all sizes.
These curved roads also naturally control speed, slowing traffic and preventing dangerous descents. They require drivers to focus on sharp turns, reducing fatigue and keeping them alert. Furthermore, zigzag roads are better for the environment, as they manage water runoff and prevent erosion, which could be exacerbated by a straight road cutting through the mountain.
While straight roads may seem cheaper initially, they require extensive infrastructure like retaining walls and drainage systems. In the long run, zigzag roads are more cost-effective due to their lower maintenance costs. Ultimately, zigzag roads offer a safer, more sustainable, and more economical solution for navigating mountainous terrain.
