Southward growth of Calgary had turned the small rural highway (it remained a 2-lane rural arterial road for many years) into an urban street that was not suited for high traffic volumes.

[citation needed] Until the late 1990s, all of Highway 22X within the City of Calgary went by the name "Marquis of Lorne Trail" (with the French variant "Marquis de Lorne" used frequently by the city, although signage retained the English version), until the owners of Spruce Meadows successfully lobbied the city to rename the portion west of Macleod Trail after the internationally known show-jumping facility.

In 2009, the province announced plans to complete the southeastern portion of Stoney Trail south from Highway 1A.

This project included major upgrades to the Marquis of Lorne segment of 22X west from approximately 88th Street to Macleod Trail.
