Major Mackenzie Drive: Highway 400 to Highway 50

Transforming Major Mackenzie Drive

Section 3, proposed rendering shows how the intersection and bridge will align with the future Major Mackenzie Drive.

The Regional Municipality of York is investing in building a safe, efficient and reliable Regional transportation network for all users. Improvements to Major Mackenzie Drive from Highway 50 to Highway 400 in the City of Vaughan are underway to accommodate growth, improve traffic flow and provide public transit connections and more travel options for all.

Improvements include:

  • Widening Major Mackenzie Drive to six lanes
  • Providing a connection to the proposed Highway 427 extension
  • Realigning a portion of Major Mackenzie Drive between the Canadian Pacific Railway tracks and Highway 27 to provide a continuous connection across Highway 27
  • Building new bridges including a 150-metre bridge over the Humber River and a bridge over the existing level crossing of the Canadian Pacific Railway tracks
  • Installing multi-use paths, sidewalks and street lighting
  • Replacing old culverts with larger structures
  • Improving intersection accessibility
  • Installing wildlife fencing and wildlife culverts between Islington Avenue and Pine Valley Drive

Construction Update

Section 1: Pine Valley Drive to Highway 400

  • Construction is complete

Section 2: Islington Avenue to Pine Valley Drive

  • Construction will begin once land is acquired and is scheduled to be completed in 2021

Section 3: Canadian Pacific Railway tracks to Islington Avenue

  • The majority of road work between Highway 27 and Islington Avenue is scheduled to be completed this year. A water main is being installed on the south side, which will be located under the future south boulevard.
  • Humber River bridge construction is well underway. To allow for the river’s flood waters to pass underneath the bridge, the bridge is higher than the existing road intersection at Major Mackenzie Drive and Highway 27. As such, the intersection will be raised this summer to match the level of the bridge.
  • To build the bridge over the Canadian Pacific Railway tracks, traffic has shifted to a temporary Major Mackenzie Drive detour and will be in place for at least two years. Large amounts of soil are being trucked in and placed to build the road leading up to the bridge on either side. This work is scheduled to take approximately four months to complete. Once in place, there could be up to a year of inactivity at this location as the ground underneath settles.
  •  Construction is scheduled to be completed in 2021

With the girders in place, the Humber River bridge deck can be constructed this spring.

Section 4: Highway 50 to Highway 427 extension

  • Design is underway and utility relocation will commence later this year
  • Construction is expected to begin in 2020 and is scheduled to be completed in 2021
