Arterial highways carry high volumes of traffic over long distances with widely-spaced grade-separated interchanges. They are the backbone of a network of arterials, collectors, and local streets.
Grade-separated interchanges take many forms, including: diamond; trumpet; single-point urban diamond full and, partial cloverleaf; and fully directional interchanges. The interchange form that is most appropriate is a particular case is a function of many factors: long-range traffic forecasts, topography, wetlands and other environmental features, right-of-way, community impacts, and construction cost.
