Bow Trail
Bow Trail is an expressway in the southwest quadrant of Calgary, Alberta. It gets its name from the Bow River, which runs through the city north of the road itself. It runs from downtown Calgary, where the westbound traffic continues from 6 Avenue SW and eastbound traffic becomes 9 Avenue SW, past Stoney Trail to 101 Street SW at the city limits.
Bow Trail, along with 17 Avenue SW, are two major thoroughfares linking downtown Calgary to the west end of the city. In the late 1960s, there were plans to extend Bow Trail along a more northerly alignment before linking with Memorial Drive east of downtown. Fierce opposition to freeways running through downtown Calgary scuttled the plans, and the C-Train gained favour.
History
Prior to it being named Bow Trail, the road west of 33 Street SW was known as Banff Coach Road. The road was rerouted with westbound expansion, with Bow Trail being rerouted on a more southerly route west of Sarcee Trail. The remainder of the road exists today, as Old Banff Coach Road. East of 33 Street SW and west of Crowchild Trail, Bow Trail conformed to Calgary's street numbering conventions, and was known as 12 Avenue SW.In 2004, the city of Calgary conducted a traffic volume study along Bow Trail that found the four lane road inadequate. Consequently, an additional westbound lane was added between 33 Street and Sarcee Trail by 2006. The section between Sarcee Trail and Strathcona Boulevard was widened and landscaped by 2007, while the intersection with Sarcee Trail was improved. Although an interchange with Sarcee has been proposed for many years, as of 2018 none is planned; the city built one further south at Sarcee and 17th Avenue S.W. in the late 2000s instead.
In 2010, construction of the west leg of the C-Train light rail transit system begun along the Bow Trail between Crowchild Trail and 33 Street West. This involved widening Bow Trail east of 33rd Street, and a slight realignment at 33rd and Bow to allow room for the tracks and a tunnel entrance. Construction was completed in December 2012.
Until 2023, Bow Trail ended at 85th Street, though the road at the time continued for a short way beyond as 12th Avenue S.W., an unpaved rural access road. In 2023, an interchange with the then-recent southwestern leg of the Stoney Trail ring road was added with Bow Trail officially ending at 101 Street SW at the city limits.
