Difference Between Flyover and Bridge

What Is Flyover?


Flyovers, over a flyover, underpasses, overpasses, etc. are some examples of the engineering marvels that allow for the effort of people and saving of time, vehicles, and even trains.

Normally flyover is made over water bodies like rivers, but over bridges are meant into provide the roadway for pedestrians and even vehicles over a railway line or even under the flyover.

The flyover is a concept that allows roads to be built over roads to facilitate faster movement of vehicles and people in this age of congested traffic at metro cities.

There are differences in overbridge and flyover.

The flyover is also known as the overpass that is built over an existing road or the railway in such a manner that it crosses another road or railway.

It helps in saving the time for a commuter whether they are pedestrians or running automobiles and have become very commonplace at big cities these days.

However, Criticisms of flyovers as they lead to wastage of precious space at this form of huge pillars that go up on the existing road.

But their benefits outweigh their shortcomings as they facilitate more efficient and faster transport of people and vehicles.

What Is Bridge?

A Bridge, a connecting structure, create bonding between different disconnected parts of a country, two banks of the ocean, or parts of two countries.

A Bridge is a structural marvel which is


Information on Bridge.

This first bridges made by humans were probably spans of planks or wooden logs and eventually stones, using a crossbeam arrangement and simple support.

Most of these early bridges couldn’t support heavy weights or withstand strong currents.

It was these inadequacies that led to the development of better bridges. The oldest surviving stone bridge in China is the Zhaozhou Bridge, built from 605 to 595 AD during the Sui Dynasty.

The bridge is also historically significant as it is the world’s oldest open-spandrel stone segmental arch bridge.

Difference Between Flyover and Bridge

1The bridge stands for the structure that arranges passage over an obstacle devoid of sealing the way underneath. The necessary passage may belong to a road, a railway, pedestrians, a canal or pipeline. The obstacle to be passed may range from a river, a road, railway or a valley.Flyover stands for a bridge that bears one road or railway line over another either including or excluding supplementary roads for making communication among the two.
2This is also used for connection purposes but it is usually built over roads as an overpass.The bridge is constructed to connect the two different points.
3They are generally constructed for road vehicles.Bridges are mainly utilized for maneuvering traffic across the obstruction. They are also applied to navigate pipelines and other forms of transport.
4They are generally constructed over road junctions, roads, streets, etc.Several obstructions on which the bridge is constructed vary from seas, rivers, valleys, etc.
5A flyover is constructed for the purpose of making traffic less.The Bridge has constructed for short distance & bypass
6Flyovers are built over man-made structures such as roads, intersection, etc. to prevent congestion, and provide a more convenient way to navigate over the traffic.A bridge is built for less transportation cost and saving time
7Flyover connected to a junction point or rich point like station point connected. The length of the bridge totally depends on the Gap between the two points.
8The flyover is built in those areas where the roads are congested.The Bridges was mainly constructed over the River, Valley etc.
