What does flyover mean?
A flyover is a bridge built to carry one road or railway above another, letting streams of traffic cross without stopping or intersecting. The term is chiefly British; North Americans describe precisely the same structure as an 'overpass', making this one of the more striking transatlantic splits in engineering terminology. Flyovers are central features of modern road design, appearing at motorway junctions, city interchanges, and rail crossings wherever planners need to keep vehicles moving smoothly. While functionally admired for easing congestion, they are not always loved aesthetically — critics sometimes cite them as symbols of car-dominated urban planning, and many cities have demolished or landscaped them in regeneration schemes. A secondary, less common sense describes an aircraft's ceremonial or symbolic flight over a location, though the word 'flypast' is more usual there. For anyone reading British news or travel writing, 'flyover' is an essential piece of vocabulary.
nounA bridge that carries one road across another road or railway without an intersection, allowing traffic to pass above the crossing route. In North America the same structure is typically called an 'overpass'.
- A raised road or railway bridge carrying one route across another so traffic can pass without an intersection.
- (British, also) a low pass made by aircraft flying over a place, especially a ceremonial flypast — a minor secondary usage.
"The new flyover at Junction 12 has cut rush-hour congestion almost in half."
"Commuters cheered when the long-delayed flyover finally opened to traffic on Monday."
"From the window of the train we could see cars streaming along the flyover above the freight line."
Regular plural formation applies; multiple structures are simply referred to as flyovers.
"The city has announced plans for three new flyovers along the eastern bypass."
The exact same concrete bridge is a 'flyover' in Britain and an 'overpass' in America — proof that even civil engineering can't agree on English.

Etymology of flyover
Flyover is a compound of two native English elements: the verb 'fly' (from Old English 'fleogan', meaning to move through the air) and 'over' (from Old English 'ofer', meaning above or across). It emerged in the late nineteenth and early twentieth centuries as railways and then motor roads began to be grade-separated, with the image of traffic 'flying over' an obstacle lending the name its appeal. Its North American counterpart 'overpass' was formed from the same 'over' element, making the two words close cousins rather than direct translations.
How flyover is actually used
'Flyover' is the everyday British term for what Americans call an 'overpass'; using it in the US sounds distinctly British but is understood. The word carries no strong connotation, though in urban planning debates 'flyovers' are sometimes criticized as unattractive car-centric infrastructure. The aerial sense (an aircraft's ceremonial flight over a site) overlaps with 'flypast', which is the more common term for that usage.
Easily confused with flyover
An overpass is the identical structure as a flyover, but 'overpass' is the standard North American term while 'flyover' is the standard British one.
An underpass carries traffic beneath the crossing route, whereas a flyover carries it above.
A flypast is an ceremonial flight of aircraft over an event, unrelated to road bridges despite the similar name.
