Expressways are high-capacity roads designed for fast-moving traffic. They typically have multiple lanes in each direction and limited access points, meaning vehicles can enter and exit only at specific interchanges. This design helps reduce congestion and allows for higher speed limits compared to regular roads. These roads are often equipped with features like overpasses, underpasses, and sound barriers to enhance safety and minimize noise. Expressways are crucial for connecting cities and regions, facilitating the efficient movement of people and goods. They are also known as freeways or motorways in different parts of the world.
