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

As part of the Bow Trail widening project, interim improvements will be made to the intersection of Bow Trail and 85 Street S.W. These improvements include extending the southbound left turning lane on 85 Street north of Bow Trail and adding a second westbound left turning lane on Bow Trail. Construction is scheduled to begin in June or July this summer and is expected to be complete in August. Periodic lane closures and speed reductions may occur, mainly during off-peak hours. We thank you for your patience.

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. Further work on the intersection at Bow Trail and 85 Street will also be occurring in 2018 and the plans 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 walls are required, as guided by The City’s Surface Noise Policy.

Design

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

Project timeline

Design: Spring 2017 – late 2017
Construction on initial intersection improvements: Summer 2017 – late 2018
Project completion: Late 2018
