This article was originally published on April 15 2015. It was updated on March 5 2016 to reflect newly found information about the City’s earliest plans for bypass routes in 1952 and 1953.
The City of Calgary and the Province of Alberta variously point to planning and studies from 1959 or the 1970s as the origin of the Southwest Ring Road.1 While these studies mark important milestones in the history of this road, particularly around planning for the current iteration, the truth is that the concept is a much older one than that.

Early efforts had been undertaken to plan for roads encircling Calgary’s downtown area, notably the town plan by Thomas Mawson in 1914, though these were not acted upon at the time. It wasn’t until a post-world war two explosion in population growth and vehicle ownership in Calgary had occurred that the issue of bypass roads would again be brought to the fore.
The 11-year period between 1952 and 1963 constitute the practical origin of Calgary’s bypass road system, and would see incredible effort and progress on this issue: from outright rejection, to intensive planning, and finally to construction of Calgary’s first southwest bypass route.
The Earliest Southwest Ring Road Plans
In order to address the rapid growth experienced in the post-war years, the City of Calgary began the process of creating a General Plan for the city in the late 1940s. By 1951, an interim report on the General Plan was produced, which included descriptions of primary roads planned for Calgary. A major route following 50th avenue SW across the Elbow river along the City’s southern edge and 14th street SW heading north across the Bow river2 was noted, and was intended to connect the Macleod and Banff trails and act as a bypass around the City’s core.
This interim report was followed by a preliminary major roads plan that was presented to City Council in the winter of 1952. The plan contained many of the same routes as the earlier General Plan interim report, though the southwest bypass was now envisioned along 24th street SW/Crowchild Trail, rather that 14th street SW, as the north-south portion of the route.3

Although these initial planning efforts focused on routes contained within the City’s limits, plans were simultaneously being prepared on a wider scale; the City’s major road plan was not intended as a final document, but was intended to be continually updated and expanded as conditions demanded.
The City’s planning department had earlier drafted a different map in 1952 that for the first time described the series of planned bypass roads as a ‘Ring Road System’, and indicates, though does not fully depict, a southwest bypass located on 37th street SW.4 This was an internal working document that was not intended for the public, and shows how the City had begun to look outside of it’s city limits at more regional roads.
In late 1953 a further revision was completed, which for the first time fully detailed a Southwest Ring Road route around the west edge of the Glenmore reservoir.5 Comprising of 90th avenue SW on the south and 53rd Avenue/Sarcee Trail on the west, this version of the Southwest Ring Road shares little in common with the modern route, though the use of the Sarcee Trail right-of-way and a crossing through the Weaselhead would remain part of the Southwest Ring Road plans for decades to follow.

By the early 1950s the City had a defined, though extremely fluid, ring road plan. Work on the plan by the City of Calgary would continue for a number of years yet, though putting the scheme into action could not be done by the City alone; implementation would require a partner in the form of the Provincial government.
