A flyover bridge, also known as an overpass or an elevated roadway, is a type of bridge that is built over an existing road or intersection. It allows traffic to pass over or under existing roadways or other obstacles, such as waterways or railways, without having to stop or cross at the same level. Flyover bridges are often used in urban areas where there is heavy traffic congestion or where roads intersect at different levels. They can help reduce traffic congestion by allowing vehicles to move more quickly and efficiently through an area. They can also improve safety by reducing the risk of collisions at intersections.
Some key points about flyover bridges include:
- A flyover is a high-level road bridge that crosses over another railroad or highway intersection or an existing road.
- It is also called an "overpass".
- Flyovers are constructed to allow for safe passage over obstacles.
- A bridge and a flyover differ from one another depending on how they will be used and where they will be constructed.
- There are two types of flyovers used for traffic management: simple flyovers and cloverleaf flyovers.
- Simple flyovers are used for fast traffic, which is made to pass at a high level by a bridge, providing ramps on both the approaches, while slow traffic is made to pass underneath.
- Cloverleaf flyovers are constructed to link two separate locations, and they may be found naturally in places like valleys, rivers, seas, or other water bodies.
