What is the difference between bridge and flyover?

A bridge and a flyover are similar structures, but they differ in their purpose and design.

Bridge

A bridge is a structure built to span a physical obstacle such as a river, road, or valley. It provides a way for people, vehicles, or trains to cross over the obstacle. Bridges are usually permanent structures and can be constructed from various materials like concrete, steel, or wood.

Flyover

A flyover is a type of bridge that is specifically designed to allow one road or railway to pass over another without them intersecting. Flyovers are often used in urban areas to reduce congestion and improve traffic flow. They can also be used in rural areas to allow roads to cross over natural obstacles like rivers or valleys.

Key Differences

- Purpose: Bridges are used to cross obstacles, while flyovers are used to allow one road or railway to pass over another.

- Location: Bridges can be located anywhere, while flyovers are typically found in urban areas or where roads or railways intersect.

- Design: Bridges can have various designs and can be constructed from different materials. Flyovers are specifically designed to allow for the passage of vehicles or trains overhead and are usually made of concrete or steel.

Overall, bridges and flyovers are both structures that facilitate movement across obstacles. While bridges provide a way for people, vehicles, or trains to cross any kind of physical obstacle, flyovers are specifically designed to allow for the smooth flow of traffic in urban areas or where roads intersect.
