A highway interchange is a junction where two or more roads meet, allowing vehicles to switch from one road to another without stopping. These interchanges are designed to improve traffic flow and safety by minimizing the need for traffic signals or stop signs. They often include ramps that connect different highways or roads, enabling smooth transitions for drivers. Interchanges can vary in design, with common types including diamond, cloverleaf, and stacked interchanges. Each design serves different traffic volumes and patterns, helping to manage the movement of vehicles efficiently. Properly designed interchanges are crucial for reducing congestion and enhancing travel times on major routes.
