Stage Three includes road widening, Terwillegar Drive and Anthony Henday Drive Interchange upgrades, dedicated transit lanes and a shared pathway.

Project Update - November 2025

Early works on Stage 3 have been completed. Work included building the head slope fills for the new Terwillegar Drive roadway bridge and a new separated pedestrian bridge. Completing the head slope fills allows the ground to settle before main construction work, which is anticipated to begin in spring 2026.

Stage 3 will include:

  • A new roadway bridge carrying northbound Terwillegar Drive over Anthony Henday Drive.
  • Reconfiguration of the existing bridge to carry southbound Terwillegar Drive over Anthony Henday Drive.
  • Two new loop ramps connecting southbound Terwillegar Drive to eastbound Anthony Henday Drive and northbound Terwillegar Drive to westbound Anthony Henday Drive.

Additional improvements include:

  • Widening Terwillegar Drive/170 Street to six lanes (three in each direction), including new transit lanes.
  • A new separated shared-use path bridge over Anthony Henday Drive, connecting South Terwillegar to Windermere Boulevard, east of Currents Pointe.
