An expressway is a high-capacity, high-speed road designed for through traffic with limited access points. Unlike regular roads with driveways and frequent intersections, expressways restrict access to designated interchanges, allowing uninterrupted higher-speed travel. Expressways may or may not have full grade separation (overpasses/underpasses at all crossings)—some use traffic signals at major intersections while limiting other access. Examples include Calgary's Deerfoot Trail and Edmonton's Whitemud Drive. The distinction between expressways, freeways, and highways varies by jurisdiction and isn't always consistent. Expressways carry high traffic volumes efficiently but can divide neighbourhoods, generate noise, and contribute to urban sprawl by enabling longer commutes. Planning for expressways involves balancing mobility benefits against community impacts, costs, and land use implications. Some cities have removed or buried expressways to reconnect urban areas.
