Project Update - April 2026

With site preparation now complete, construction on Stage 3 of the Terwillegar Drive Expansion Project will begin this spring and is expected to take approximately two years.

This stage includes a new interchange and pedestrian/cyclist bridge over Anthony Henday Drive, along with corridor upgrades to support future traffic, transit and active transportation needs.

Traffic impacts:

  • During construction, two lanes of traffic will be maintained in each direction.
  • Short-term daytime and occasional nighttime lane closures may be required.
  • Minor impacts to Anthony Henday Drive, including temporary lane closures and reduced speeds
