What is a Flyover?

A flyover is a type of bridge or overpass that allows traffic to pass over another road, railway line, or other obstacle without stopping or slowing down. It is typically elevated above the ground and has no at-grade intersections, meaning that traffic can continue to flow underneath it without interruption.

Flyovers are commonly used in urban areas where there is a high volume of traffic and limited space for roads to intersect. They help to improve traffic flow and reduce congestion by allowing vehicles to bypass busy intersections and continue on their route without delay.

There are different types of flyovers, including:

1. Elevated flyovers: These are the most common type of flyover and are elevated above the ground on pillars or columns.
2. Deck-type flyovers: These are similar to elevated flyovers but have a flat deck that spans over the obstacle, rather than being elevated on pillars.
3. Underpass flyovers: These are also known as "flyunder" and are located underneath the road, allowing traffic to pass underneath without stopping.
4. Interchange flyovers: These are used at interchanges where two or more highways meet, and allow traffic to continue on their route without stopping or slowing down.

Overall, flyovers play an important role in improving traffic flow and reducing congestion in urban areas, and are a common feature of many modern cities' transportation infrastructure.
