What is the main purpose of a cloverleaf interchange?

The main purpose of a cloverleaf interchange is to facilitate smooth merging and exiting from highways. These interchanges are designed with loops that allow vehicles to transition between roads without the need for traffic signals or stop signs. This design helps to reduce congestion by enabling traffic to flow freely in multiple directions, which is crucial for highways where high-speed travel is common. By providing dedicated lanes for merging and diverging, cloverleaf interchanges enhance traffic efficiency and safety, allowing drivers to change routes seamlessly. This structural design is particularly beneficial in areas where multiple highways intersect, ensuring that vehicles can maintain higher speeds while transitioning to other routes.
