Bow Trail widening and intersection improvements

Subscribe for email updates Email the project team

The City is planning to widen Bow Trail to four lanes between 85 Street S.W. and Old Banff Coach Road, as well as improving the intersection at Bow Trail and 85 Street S.W. These upgrades will provide for a better road network by accommodating existing and future traffic volumes in the area.

Project update

The City will be widening Bow Trail to four lanes between 85 Street S.W. and Old Banff Coach Road in 2018. The design of this project began in April 2017, and is expected to be complete by December 2017. In summer 2017, The City made some interim improvements to the intersection of Bow Trail and 85 Street S.W. Further work on this intersection will also happen in 2018. The plans will include widening 85 Street to two through lanes north of Bow Trail to match the road alignment to the south, including a separate left turning lane for drivers travelling eastbound on Bow Trail. Construction on this project is anticipated to start in spring 2018 and will be completed by the end of 2018.

About the project

Widening Bow Trail and improving the intersection at 85 Street S.W. better manages the current and future traffic volume in the area.

This particular project involves a number of features:

  • Widen Bow Trail from two to four lanes between Old Banff Coach Road and 85 Street S.W.
  • Improve the intersection at 85 Street and Bow Trail by adding dedicated left- and right-turn lanes as well as through lanes in each direction.
  • A pathway along Bow Trail, connecting the pathways on Old Banff Coach Road and 85 Street S.W.
  • A noise study to determine if noise barriers are required, as guided by The City’s Surface Noise Policy.


The following drawing shows an overall view of the area. We will update this section with designs as the project progresses.
