Expressways are high-capacity roads designed for fast-moving traffic, typically featuring multiple lanes in each direction. They are built to connect major cities and regions, allowing for efficient transportation of goods and people. Unlike regular roads, expressways have limited access points, which helps reduce congestion and improve safety. These roads often include features such as overpasses, underpasses, and interchanges to facilitate smooth traffic flow. Traffic signals and stop signs are generally absent, allowing vehicles to travel at higher speeds. Expressways play a crucial role in modern transportation networks, supporting economic growth and mobility.
