An overpass is a bridge that allows one road to pass over another road or railway. This structure helps to keep traffic flowing smoothly by preventing vehicles from stopping at intersections. Overpasses are commonly found in busy urban areas where many roads meet, making it easier for drivers to navigate without delays. These bridges are often designed with safety in mind, providing clear visibility for drivers and pedestrians. Some overpasses even have walking paths or bike lanes, allowing people to cross busy roads safely. Overall, overpasses play a crucial role in modern transportation systems, helping to reduce congestion and improve travel times.
