A bridge and a flyover are both structures built to allow vehicles and pedestrians to cross over an obstacle, such as a body of water, a valley, or a busy intersection.
However, the main difference between a bridge and a flyover is that a bridge spans horizontally over an obstacle, while a flyover is a raised roadway that passes over other roads or highways at different levels, and is typically used to reduce congestion and improve traffic flow in urban areas.
Bridges can be either simple or complex in design, and may include supports or piers to provide structural stability. Flyovers, on the other hand, are usually built as elevated ramps or loops to allow vehicles to bypass traffic signals or other intersections.
In short, a bridge is a structure that spans horizontally over an obstacle, while a flyover is a raised roadway that passes over other roads at different levels.
