Managing the construction zone:

As construction continues here's what you can expect along Crowchild Trail (between Bow Trail and 5th Avenue N.W.):​

  • Reduced speed limits (50 km/hr in construction zones unless otherwise indicated).
  • Narrowed traffic lanes to make space for crews.
  • Intermittent single and double lane closures along Crowchild Trail during weekday off-peak hours (Mon. to Fri. between 9 p.m. - 5 a.m.)
  • Intermittent single and double lane closures along Crowchild Trail on weekends (beginning Fridays at 9 p.m. and ending Mondays at 5 a.m.)
  • Lane shifts, re-alignments and new traffic patterns along northbound and southbound Crowchild Trail (between Bow Trail and Memorial Drive [including over 10 Avenue S.W.]).
  • Intermittent lane closures and traffic shifts along Bow Trail, Memorial Drive, Kensington Road, and 5 Avenue N.W.
  • An ongoing detour along 10 Avenue S.W. detour.
  • Periodic closures of the westbound 10 Avenue S.W. ramp (from Bow Trail S.) - use Bow Trail as detour
    • Business access via westbound 10 Avenue S.W.
  • Lane and ramp closures in the area, detours, protruding manholes, uneven road surfaces, and flaggers/police officers on-site directing traffic.

Tree impacts

While we make every effort to avoid impacts to trees, this March you'll notice some tree removals take place. Rest assured that replacement trees are being planted and in fact, by the time this project has been completed of the 129 trees that will have had to be removed, 338 will have been replanted as part of our compensation and restoration plan.


Business access

We are committed to keeping business accesses open throughout construction.

Please note that some business accesses have been modified slightly; these changes have been reflected accordingly via on-site signage.

All local businesses remain open during construction including (but not limited to):

  • Mercedes-Benz Downtown Calgary - Service and Parts
  • MDR Restoration Services
  • Magiclean/Kilroy Home Services
  • Legacy Group of Companies
  • Mars Environmental Services
  • MJ Systems
  • Courtney Automotive
