First appearing on plans together nearly 60 years ago, and shown as connected in every major road plan since, 90th avenue SW and the Southwest Calgary Ring Road have a long and inseparable history. The connection of these two roads together, initially planned out of convenience, and later out of necessity, continues to play a significant role in the history of the ring road. Calls to keep 90th avenue from being connected to the ring road have been heard in recent years, and it is important to understand the history of this road, and why the connection of 90th avenue is seen as an indispensable part of the ring road plan.
The Origins of 90th Avenue SW
90th avenue is an arterial road in Calgary’s southwest, south of the Glenmore Reservoir, that has existed in some form or another since the early days of the City. Early settlers in the region traveled its path to access their land, and by the early 20th century, a dirt road had been created which served a small number of homesteads in the area. This arrangement, pictured above in 1953, went largely unchanged for many years. When the foreseeable encroachment of an expanding City of Calgary finally necessitated it, bigger plans for the road were initiated.
Forward Planning and a Growing City
In the early to mid 1950s the City had begun to more fully embrace a civic planning program; one that was more forward looking than had been undertaken in decades. The City was creating plans for areas that were then rural, but would one day be developed as part of a rapidly-growing City. The earliest modern plan for 90th avenue can be traced back to 1953 when the City created it’s earliest internal Ring Road plan. 90th avenue SW between Macleod Trail and 37th street SW was at that time an integral part of the Ring Road, and formed the southern portion of the City’s first complete Southwest Calgary Ring Road route.

This configuration did not last long, and soon the main Ring Road route continued south, beyond 90th avenue SW. By 1956 a masterplan for the development of parks around the Glenmore Reservoir was developed by the City (shown below), and included a modified 90th avenue SW proposal. These plans mark the first time that plans for the Southwest Calgary Ring Road and 90th avenue SW were shown to the public.
Then called ‘South Glenmore Drive’, 90th avenue was depicted much as we know it today, running from 14th street SW to 37th street SW, where it connected directly to the ring road. This basic layout was retained in Calgary’s first approved transportation plan, 1959’s Calgary Metropolitan Transportation Plan (shown below as 92nd avenue).
