What is a disadvantage of roadways oriented perpendicular to the slope?

Roadways that are oriented perpendicular to the slope can lead to the creation of steep roads, which is a significant disadvantage in terms of road design and safety. Steep roads often create challenges for vehicular movement, especially in adverse weather conditions, as they can increase the risk of vehicles losing traction or sliding. Additionally, they can be more difficult for pedestrians to navigate, especially for those with mobility challenges.

Furthermore, steep slopes on roadways can lead to increased erosion and runoff issues, which complicate long-term maintenance and infrastructure stability. They can also necessitate more extensive drainage solutions to manage surface runoff effectively, which can increase construction costs and environmental impact.

In contrast, roads that follow the contour of the land are typically designed to minimize steep grades, which can facilitate better drainage, enhance driver safety, and reduce the overall environmental impact. Thus, the gradual shifts in elevation not only accommodate safer travel but also contribute to an effective stormwater management plan, contrasting with the disadvantages of approaching roadways perpendicular to slopes.
