The Region of York and the City of Vaughan are closing

• Highway 7 between Edgeley Boulevard and Jane Street

— near the site of the future Vaughan Metropolitan Centre Station — from 3 until 4 a.m. Tuesday, July 31,

while TTC contractors move heavy equipment from the north side of the roadway to the south side. The move is part of the ongoing project to extend the 1 Yonge - University - Spadina subway northwestward beyond Downsview Station to York University and Vaughan.

York Regional Police officers will make sure that traffic flows safely and redirect traffic to alternate routes.

The City of Vaughan has amended its noise by-law to allow the contractor to work overnight and weekends, if necessary, to reduce disrupting traffic over a long term and to keep the project on schedule.

If the contractors need more time to complete the work, the activity may delay early-morning buses operating along York Region Transit’s Viva orange or 77 Highway 7 routes or Brampton Transit’s 501 Züm Queen route.

The contractors previously closed the highway to move equipment across the highway early Thursday, May 24 and early Monday, June 25.
