Yellowhead Trail is a 24.6-kilometre (15.3 mi) expressway segment of the Yellowhead Highway in northern Edmonton, Alberta, Canada. It carries a significant amount of truck traffic to and from the industrial areas of north Edmonton and serves as a key commuter route for the bedroom communities of Stony Plain, Spruce Grove, and Sherwood Park, carrying nearly 80,000 vehicles per weekday in 2015. A suburban bypass of the route was completed when the northeast leg of Anthony Henday Drive (Highway 216) opened in late 2016, providing an alternate route through north Edmonton.

A limited-access road, known by various terms worldwide, including limited-access highway, dual-carriageway, expressway, and partial controlled-access highway, is a highway or arterial road for high-speed traffic which has many or most characteristics of a controlled-access highway, including limited or no access to adjacent property, some degree of separation of opposing traffic flow, use of grade separated interchanges to some extent, prohibition of slow modes of transport, such as bicycles, horse-drawn vehicles or ridden horses, or self-propelled agricultural machines; and very few or no intersecting cross-streets or level crossings. The degree of isolation from local traffic allowed varies between countries and regions. The precise definition of these terms varies by jurisdiction.
