An overpass is a type of bridge that allows one road or pathway to pass over another. It is commonly used in urban areas to help manage traffic flow, reduce congestion, and improve safety by separating different levels of transportation. Overpasses can be found in various forms, including pedestrian overpasses and highway overpasses. Overpasses are often constructed using concrete or steel and are designed to support the weight of vehicles and pedestrians. They are essential components of modern infrastructure, facilitating smoother travel and connecting different parts of a city or region. Examples of overpasses include those found in major cities like New York City and Los Angeles.
