The difference between Bridge and Flyover is based on the purpose of its usage and the location where it is built.
1- The drainage structure which facilitates a communication route for carrying road or railway traffic across an obstruction or depression with or without water is called a bridge.
2- A bridge is a structure that is built over natural obstructions such as rivers, valleys to connect two locations separated by these obstructions.
3- Bridges are further classified on the basis of their purpose, lifespan, materials, span, etc.
4- Bridges are used for navigating traffic across the obstruction, navigating pipelines, and other forms of transport.
A flyover is also known as an overpass that is built over an existing road or a railway in such a manner that it crosses another road or railway.
1- The flyover is an overpass, a high-level road bridge that crosses over a highway interchange or intersection.
2- It is a structure that joins two or more points that are separated by accessible routes or a man-made structure to cut the traffic for a faster mode of travel.
3. They are usually made over road junctions, roads, streets, etc.
4- The name itself suggests that you are flying over a traffic zone.
5-They are usually built for road vehicles.
6- The flyover is constructed for the purpose of making traffic less.
7- Flyovers are built over man-made structures such as roads, intersections,s, etc. to prevent congestion, and provide a more convenient way to navigate over the traffic.
