Urban Interstate System

The Urban Interstate System consists of high-capacity highways designed to connect cities, suburbs, and industrial areas efficiently. These roads typically have multiple lanes, controlled access via ramps, and limited intersections, allowing for smooth, high-speed travel over long distances within urban regions. Their purpose is to facilitate quick movement of traffic, reduce congestion, and improve safety by separating through traffic from local streets. Built to accommodate large volumes of vehicles, these highways are vital for economic activity, emergency response, and daily commuting, serving as the backbone of urban transportation infrastructure.
