Bow Trail widening and intersection improvements


Project update: September 3, 2019

Crews are in the final stretch on completing the remaining work on the new and improved Bow Trail. Until September 10, 2019 crews will be working in the median, with one travel lane in each direction on the north and south side.

The wet spring and summer, has pushed completion to mid-September. Here's a breakdown on the items underway over the next few weeks (Phase 1) and into the fall (Phase 2).

Phase 1:
Complete major work, between 85 Street S.W. and Old Banff Coach Road

  • Old Banff Coach Road intersection
    • Extending the left-hand turn lanes to Strathcona Blvd​ from Bow Trail
    • Adding a third left hand turn lane to Bow Trail, from Old Banff Coach Road
  • 85 Street S.W. intersection
    • Add second left hand turn lane in all directions
    • Add sidewalk to west side of intersection
  • Final paving on the new westbound lanes
  • Pathway
  • Landscaping and tree planting (800 trees)

Phase 2:
Complete major work, west of 85 Street S.W.

  • Site grading and road construction to the Transportation Utility Corridor

Construction highlights - 2019

  • Complete curb and paving on eastbound lanes (single lane closures expected)
  • Pave final layer on westbound lanes (single lane closures expected)
  • Install pedestrian crossing, near 77 Street S.W.
  • Finish intersection work at Bow Trail/85 Street S.W. and Bow Trail/Old Banff Coach Road Finish landscaping on north and south sides of Bow Trail
  • Complete and pave pathway on north and south sides of Bow Trail

Watch for:

  • Single lane closures outside of rush hour directions, on Bow Trail and in the dual turn lanes at the 85 Street S.W. and Old Banff Coach Road intersections.
  • A 50km/hr speed limit through the construction zone until crews complete work in summer 2019.
  • With the closure of the regional pathway adjacent a detour is in place for people walking and cycling through the area, until spring 2019 To see the detour please visit the pathway and bikeway map​.

Construction work typically takes place from Monday to Saturday, from 7 a.m. until 7 p.m., and will be conducted in accordance with the Community Standards Bylaw. Some Sunday work may be required.

Additional construction updates will be provided as they come available.

Please note: All construction is weather-dependent, so construction times could change.

About the project

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.

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 Blvd.


Information session roll plans

On March 22, we hosted an information session, where we showcased the following designs. Based on the comments we heard, we've revisited the landscaping plans to see where we can further improve the various trees and other plantings.

Calgary's west 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.
