Project Benefits

The McKenzie Interchange Project will improve traffic flow of passenger, transit and goods movement vehicles and reduce collisions and congestion-related impacts to the economy and the environment.

Project benefits include:

  • Reductions in frequency and severity of crashes
  • Substantial travel time savings
  • Improved transit facilities, including bus-on-shoulder lanes, coordinated with cycling and pedestrian facilities
  • Improved travel time reliability
  • Reductions in idling and fuel consumption, leading to significantly lower greenhouse gas emissions
  • Improved cycling and pedestrian safety, by separating the Galloping Goose Trail from McKenzie Avenue
  • Widening of the Galloping Goose Trail to five metres (six metres in places) throughout the project
  • Safety benefits for students at nearby schools, who no longer need to walk along the shoulder of the Trans-Canada Highway or cross the highway at a traffic signal


  • Completion summer 2020

Project Design

The McKenzie Interchange Project is a partial cloverleaf. It features pedestrian, cycling and transit facilities and allows for a future Light Rail Transit corridor. This design was chosen because:

  • it is the safest, most efficient option and best meets the long-term needs of this region
  • it is the preferred option of 75% of those who participated in the public consultation.
