The exact timing for construction of the long-awaited Highway 427 extension is unknown at this point, but it’s clear there’s going to be traffic chaos in Vaughan’s west end once work gets underway:

There will be nearly a dozen temporary road closures as part of the project over the next few years.

LINK 427, the consortium hired to carry out the $616 million highway expansion, will be closing 11 roads at various times during the construction period, MTO representative Dean Kemper told Vaughan councillors June 6.

Roads to be closed include Regional Road 99, which is the temporary extension of Highway 427 from Highway 7 to Zenway Boulevard built nearly a decade ago.

Also slated for closure are McGillivray Road at Rutherford Road, which is being realigned, as well as Huntington Road at Major Mackenzie Drive and Major Mackenzie Drive east and west of Huntington.

These road closures are needed to help facilitate construction of the by 6.6-kilometre highway extension from Highway 7 north to Major Mackenzie Drive.

As part of the project, a four-kilometre stretch of Highway 427 is also being widened to eight lanes between Finch Avenue and Highway 7.

A 15.5-kilometre stretch of designated High Occupancy Toll (HOT) lanes with electronic tolling will also be installed in both directions from south of Highway 409 to north of Rutherford Road.

The HOT lanes are slated to open in 2021.

North of Rutherford, the highway extension will be six lanes wide with three interchanges at Langstaff Road, Rutherford and Major Mackenzie Drive.

LINK 427 is expected to unveil a communications plan later this month that will include a dedicated website featuring regular updates on the timing of construction and road closures as well as a schedule for a slate of public meetings to keep people abreast of what’s happening with the project.

The consortium, which is responsible for designing, building, financing and maintaining the new stretch of roadway includes ACS Infrastructure Canada Inc. and Miller Infrastructure, Dragados Canada Inc., Bot Infrastructure Ltd., MMM Group Ltd. and Thurber Engineering Ltd.
