Overbridges, also known as flyovers or overpasses, are elevated structures that allow vehicles to pass over roads, railways, or bodies of water. They are typically made of concrete or steel and can range in size from small walkways to massive highway systems. Other synonyms for overbridges include viaducts, elevated highways, and cloverleaf interchanges. Some may also refer to them as elevated crossings, elevated roadways, or elevated bridges. Regardless of what they are called, overbridges are important infrastructure elements that provide safe and efficient transportation options for people and goods.
