An overpass is a bridge or structure that allows one road or pathway to pass over another. It is commonly used to separate different levels of traffic, such as when a highway crosses over a local road, helping to avoid intersections and reduce congestion. Overpasses improve traffic flow and safety by keeping vehicles moving without the need to stop for traffic lights or signals. They are often found in busy urban areas, on highways, or at railway crossings to allow for smoother and faster travel.
