Circle Drive is a major road constructed as a ring road in Saskatoon, Saskatchewan, Canada. Its route constitutes both part of the Yellowhead Highway and Highway 11, signed as both along the entire length. It was first conceived in 1913 by the city commissioner and completed exactly 100 years later in 2013. Most of the route is a fully-controlled access freeway, however the segment between Airport Drive and Millar Avenue has at-grade intersections.
