In May 2015, a historic land transfer between Alberta and the Tsuu T’ina Nation was finalized, providing certainty that the construction of the southwest segment of the Calgary Ring Road could go forward. This will extend from Lott Creek Boulevard on Glenmore Trail/Highway 8 south to Macleod Trail (Highway 2A) and is approximately 21 kilometres long. The project will also include approximately 10 kilometres of connector road upgrades.
In June 2020, the provincial government announced the project had reached 80 per cent completion. In October, a 12-kilometre portion of the Southwest Calgary Ring Road, from Sarcee Trail to Fish Creek Boulevard, opened to traffic
The road is expected to completely open to vehicle traffic in 2022.
