A trumpet interchange is a type of highway interchange designed to facilitate the flow of traffic between two major roads. It features a series of loop ramps that allow vehicles to change directions without stopping, reducing congestion and improving safety. The design resembles a trumpet, hence the name, as the ramps curve outward like the bell of a trumpet. This interchange is particularly useful in areas with high traffic volumes, as it minimizes the need for traffic signals and stop signs. By allowing for smooth transitions between roads, a trumpet interchange helps maintain a steady flow of vehicles, making travel more efficient.
