McKnight Boulevard is a major east-west arterial road and expressway in north Calgary, Alberta, Canada. It is preceded by John Laurie Boulevard, a major arterial road in the northwest quadrant. The two roadways function together as a major crosstown route between the northwest and northeast quadrants and are part of Calgary's Skeletal Road Network.
McKnight Boulevard begins in the northwestern community of North Haven at a T-intersection with John Laurie Boulevard and 48 Avenue NW as a four lane arterial road and continues east, with speed limits ranging between 50 and 60 km/h (31–37 mph). East of Deerfoot Trail (Highway 2), McKnight Boulevard becomes an expressway, with speed limits ranging between 70 and 80 km/h (43–50 mph), to the city limits east of Stoney Trail NE (Highway 201).
It is named for William Lidstone McKnight (1918–1941), a World War II flying ace with the Royal Air Force who had spent much of his childhood in Calgary before disappearing shortly after the Battle of Britain in combat. Prior to the road being renamed in his honour, the portion of the road west of what is now Deerfoot Trail conformed to Calgary's street numbering system, and was known as 48 Avenue N, while the eastern portion was part of Edmonton Trail until the city's road network in the northeast portion of the city was revised in the 1960s.
John Laurie Boulevard from the community of Arbour Lake as an arterial road and passes through the communities of Hawkwood and Ranchlands with a speed limit of 60 km/h (37 mph). At Ranchlands Boulevard, it begins to transition to an expressway with the speed limit increasing to 70 km/h (43 mph) and becomes an expressway east of Sarcee Trail. John Laurie Boulevard continues east along the southern edge of Nose Hill Park to its eastern terminus at McKnight Boulevard.
