An interchange is a type of road junction that allows vehicles to switch from one road to another without stopping. These structures often include ramps and overpasses, enabling smooth traffic flow and reducing congestion. Interchanges are commonly found on highways and major roads, facilitating connections between different routes. There are various designs of interchanges, such as the cloverleaf and diamond configurations. Each design serves specific traffic needs and is chosen based on factors like land use and traffic volume. Properly designed interchanges enhance safety and efficiency for drivers, making travel more convenient.
