There is no point of difference between grade separator or a flyover bridge.The point is that a grade separator can either be a flyover or an under pass, that is any structure which separates the uniform grade of a running highway into two different grades.
Also considering the cost fact grade saperator is more cost effective as far as my knowledge.Flyover vs Overbridge
• An Overbridge allows movement of people or even a railway line over an existing road. It is a short structure that helps in crossing of people or railway across a road.
• A flyover is a long structure that allows a road over another road and this structure connects to another road.
• A flyover is more elaborate in design and is costlier to construct

Flyover connects two points usually as an alternate route to what is beneath. Its purpose is to shorten or quicken the travel time and ease out traffic congestion. Bridge is used to connect two points and acts as an essential link between the connecting points. Its main purpose is to establish a link between the points which is other wise inaccessible via road transport. Although neither has anything to do with natural or man-made as suggested in other answers.
