How do you make a fly over?
Concrete is placed on the lower part of the foundation, within the suspension, or the ground is used as a form. A pier column or abutment concrete is then placed. Then build the pier caps and abutments at the same time. Then we can place the steel or precast girders, or box girders.
What is a flyover structure?
An overpass (called an overbridge or flyover in the United Kingdom and some other Commonwealth countries) is a bridge, road, railway or similar structure that crosses over another road or railway. An overpass and underpass together form a grade separation. Stack interchanges are made up of several overpasses.
What is the difference between an overpass and a flyover?
So just exactly what is the difference between a flyover and an overpass? They’re kind of the same thing, said Gander. The term flyover usually refers to a ramp that is crossing another roadway, so that is generally when we use the term flyover. An overpass is any bridge that crosses another roadway.
Why are flyover built?
A flyover is constructed for the purpose of making traffic less. 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.
What are the advantages of flyover?
The flyover has been able to ease the traffic flow on the road below it as well. Before it was built, the narrow road used to be a regular pain for the commuters, especially when they had to wait to allow the VIP vehicles to pass.
What are the major part of flyover?
It consists of a deck slab, longitudinal girders, cross girders, deck beam, pier and foundation. Structural design of one span was made for all the above components.
Are flyovers bridges?
1. Flyover is an overpass, a high-level road bridge that crosses over a highway interchange or intersection. 2. It is a structure that joints two or more points which are separated by accessible routes or a man-made structure to cut the traffic for a faster mode of travel.

What are the disadvantages of flyover?
DISADVANTAGES OF FLYOVERS (2) On the other hand, the opportunity cost of constructing flyovers includes time wastage resulting from diversion of traffic to allow for the construction of the flyover. This also results in an increase in crime rates due to slow-moving traffic (World Road Association, 2019).
What is a flyover bridge?
Flyover can also be described as an overpass or a high road bridge that crosses a highway or intersection. The difference between the Bridge and Flyover is depending on the purpose of its use and the location where it is being built.
What is flyover design?
Flyover Design is done in order to implement the Flyover where land acquisition costs are high and in densely populated areas. Flyover design is a complex problem, calling ingenuity and practicality while satisfying the basic security and economic requirement.
What is the structure of a flyover?
The Flyover is of 320 m length with 32 spans, 10 m per span. It consists of a deck slab, longitudinal girders, cross girders, deck beam, pier, and foundation. Structural design of one span was made for all the above components.
What is abutment of flyover?
Abutment is the connection between the end of a flyover and a road carried by land which provides support for the final section of the flyover. A flyover is basically a bridge that crosses over another part of the road. For the construction of Flyover one should follow the following steps.
