Barlow Trail

Barlow Trail is a major arterial road in Calgary, Alberta, Canada. It is composed of multiple parts: Barlow Trail North extends north to the city limits (though Barlow Trail is a rural road north of Country Hills Boulevard), where Deerfoot Trail takes its alignment out of the city, and south to 17 Avenue SE, while Barlow Trail S leads from Deerfoot Trail at the intersection with Peigan Trail to Deerfoot Trail near the intersection with 130 Avenue SE. The portions are connected by 26 Street SE to form one continuous route.

Barlow Trail is run roughly where the fifth meridian lies in the Dominion Land Survey; the road is named for Noel Barlow, a Calgarian who served as the ground crewman to Douglas Bader, a Royal Air Force flying ace in World War II. Appropriately, Calgary International Airport is presently bounded on the east by Barlow Trail.

Barlow Trail North

Barlow Trail North serves as the primary road to Calgary International Airport. There are plans to remove the portion of Barlow Trail between McKnight Boulevard and Airport Road in order to provide space for a proposed fourth runway at the airport; the primary north-south entrance to the airport would be diverted to Deerfoot Trail to the west and Métis Trail to the east.

Prior to the construction of Deerfoot Trail, Barlow Trail served as a portion of Alberta Highway 2 from the northern city limits to 17 Avenue; Highway 2 continued southbound on Blackfoot Trail until 66 Avenue SE (the present-day Glenmore Trail) before turning southbound on Macleod Trail.
