What interchanges are not found at freeway intersections?

At freeway intersections, certain types of interchanges, such as roundabouts and signalized intersections, are generally not found due to their incompatibility with high-speed traffic and the need for uninterrupted flow. Instead, freeways typically utilize designs like cloverleafs, diamond interchanges, and directional interchanges that facilitate smooth transitions without the need for stoplights or traffic signals. These designs prioritize safety and efficiency, minimizing the potential for conflicts between vehicles.
