Why Are Manhole Covers Always Round?

Why are manhole covers always round? It’s a simple question most people never think about, but the answer reveals a smart piece of engineering that has made city streets safer for decades. In this video, we explore the real reason manhole covers are round instead of square, and how that simple shape prevents dangerous accidents, distributes heavy traffic loads, and makes maintenance easier for workers. From physics and pressure distribution to safety and practicality, this everyday object is the result of careful engineering decisions. Once you understand the logic behind it, you’ll never look at a manhole cover the same way again.
