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. The bridge is a networking device in a computer network that is used to connect multiple LANs to a larger LAN.
In computer networks, we have multiple networking devices such as bridges, hubs, routers, switches, etc, each device has its own specification and is used for a particular purpose. The bridge is a networking device that connects the larger LAN networks with the group of smaller LAN networks.

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
| Sr.No. | Flyover | Bridge |
| 1 | The 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. |
| 2 | This 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. |
| 3 | They 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. |
| 4 | They are generally constructed over road junctions, roads, streets, etc. | Several obstructions on which the bridge is constructed vary from seas, rivers, valleys, etc. |
| 5 | A flyover is constructed for the purpose of making traffic less. | The Bridge has constructed for short distance & bypass |
| 6 | Flyovers 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 |
| 7 | Flyover 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. |
| 8 | The flyover is built in those areas where the roads are congested. | The Bridges was mainly constructed over the River, Valley etc. |
FAQ: Flyovers and Bridges
What is a flyover?
A flyover, also known as an overpass, is a structure built to allow roads or railways to pass over other roads, railways, or obstacles. It helps to alleviate traffic congestion by providing a level of traffic movement that avoids intersections.
What is the difference between a flyover and a bridge?
A flyover specifically refers to a bridge built to carry a road or railway over another road or railway, typically to avoid congestion. A bridge, on the other hand, is a general term for a structure that spans an obstacle, which could be a river, valley, road, or railway.
What are the main types of flyovers?
Flyovers can be classified based on form (e.g., overpass flyover, underpass flyover) or material (e.g., composite flyover, steel flyover, concrete flyover).
What are the main types of bridges?
Bridges can be classified by form (e.g., truss bridges, arch bridges, suspension bridges) or material (e.g., composite bridges, steel bridges, concrete bridges). They can also be categorized based on their span (e.g., continuous bridges, cantilever bridges).
What are the benefits of flyovers?
Flyovers reduce traffic congestion by allowing vehicles to bypass intersections. They save time for commuters and improve the flow of traffic, which can lead to more efficient transportation in congested urban areas.
What are some criticisms of flyovers?
Criticisms of flyovers include the potential wastage of space due to large supporting pillars and the visual and environmental impact they may have on their surroundings.
Where are bridges typically constructed?
Bridges are constructed over various obstacles such as rivers, valleys, and roads. They are used to connect disparate points and facilitate transportation across these obstacles.
Why are bridges important?
Bridges are crucial for connecting different regions, improving transportation routes, and enabling the movement of people and goods across obstacles that would otherwise be impassable.
What factors influence the construction of a bridge or flyover?
Factors include the type of obstacle being crossed, the material to be used, the expected load and traffic volume, environmental impact, and the overall cost of construction.
How does the construction of flyovers and bridges impact traffic management?
Flyovers and bridges help to manage traffic by reducing congestion, improving travel times, and facilitating smoother flow through busy areas or over obstacles. They are essential for maintaining efficient transportation networks in both urban and rural settings.
