route that connected Calgary with the town of Bowness. Highway 8 began at 10 Street NW, which at the time was part of Highway 1 which passed through Downtown Calgary, crossed the Bow River along the Louise Bridge, and proceeded north and west towards Cochrane and Banff. Highway 8 travelled west on Kensington Road and Parkdale Boulevard along the north side of the Bow River, becoming Bowness Road when it entered the village of Montgomery. It crossed the original Shouldice Bridge (renamed the John Hextal Bridge) into Bowness and ended near Bowness Park. The highway was decommissioned in when Montgomery and Bowness were annexed by the City of Calgary. In the mid 1970s, Alberta introduced its Secondary Highway system (present day 500-900 series highways), and Richmond Road west of Calgary was designated as Secondary Highway 559, but was renumbered in 1979 to Highway 8. Highway 8 first followed Richmond Road into Calgary to Sarcee Trail, and followed Sarcee Trail and Glenmore Trail as an unsigned highway to Deerfoot Trail. When the residential community of Signal Hill was developed in the late 1980s and Highway 8 was realigned in 1992 to the south along a new two lane roadway which also served as a western extension of Glenmore Trail. Despite it being part of Glenmore Trail, the new roadway ended a T-intersection at the transition between the existing Sarcee and Glenmore Trails; resulting in "Glenmore Trail" commonly referring to the roadway east of Sarcee Trail and "Highway 8" referring to the roadway west of Sarcee Trail, despite both officially sharing the same designations. When the Calgary Ring Road alignment was established, it was determined that the West Leg and Southwest Leg would follow and area just east of 101 Street SW from Highway 1 south to Highway 8, travel east on Highway 8 to Sarcee Trail, and then resume heading south through the eastern perimeter of the Tsuutʼina Nation – as part of the construction the effected area of Highway 8 would become part of Stoney Trail. On October 1, 2020, upgrades to Highway 8 and the stack interchange were opened and the highway inside the ring road was redesigned as Highway 201. Future As part of the Southwest Ring Road construction, approximately Highway 8 will be twinned west of Calgary city limits, while a new Y-interchange at the eastern terminus of Highway 8 is scheduled to be completed in 2024
