Bow Trail widening and intersection improvements

Subscribe for email updates Email the project team

The City is widening Bow Trail to two lanes in each direction, between 85 Street S.W. and Old Banff Coach Road (OBCR), with additional improvements at intersections and pathways. These upgrades improve how people travel in the area and between communities now and into the future; whether you drive, take transit, cycle or walk. 

Project update

Designs are final, with work beginning on the project in spring 2018. Most of the work is scheduled to be completed by fall 2018, with some minor road work and landscaping anticipated for 2019. 

Info session

Come see the design and chat with the project team at the following information session: 

Where: First Lutheran Church, 7102 14th Avenue S.W.
Where: Thursday, March 22, 6-8 p.m.

Removing trees

Through March, we are removing a number of trees within the construction zone to make room for the new road and pathways. We will be planting approximately 766 new trees along Bow Trail, where space allows, to replace the ones we remove.   

About the project

A better Bow Trail: 


  • Add eastbound lane and westbound lane, between OBCR and 85th Street S.W., for now and future vehicle volumes
  • Extend pathways on north and south side of Bow Trail to OBCR and Strathcona Blvd. for better walking and cycling connections between communities and existing pathways. 
  • Reduce speed limit to 60km/hr on Bow Trail, providing a safer space to travel in the area.
  • Install pedestrian signal crossing at 77 Street S.W. (approx. 800m, east of 85th Street S.W.), to improve community connections.   
  • At Bow Trail/85th Street S.W. intersection: 
    • Add dual left-turn lanes all 4 directions
    • Add two through lanes in all directions
  • At Bow Trail/OBCR/Strathcona Blvd. intersection: 
    • Add a third left-turn lane, from southbound OBCR to eastbound Bow Trail
    • Lengthen the two left turn lanes from westbound Bow Trail to southbound Strathcona Boulevard.

Calgary’s southwest ring road

Is this project part of Calgary’s ring road? While the upgrades to Bow Trail are required now, the new Bow Trail design will allow a seamless transition between the future West Calgary Ring Road​ and Bow Trail.
