Metrolinx continues to upgrade the Stouffville rail corridor, including building a vehicle underpass and pedestrian bridge on Steeles Avenue East just north of Milliken GO Station, as part of the GO Expansion Program.

Starting Monday, May 3, the south side of the new underpass opens to traffic. During this next phase of construction, two lanes of traffic in each direction flow on the south side of the underpass, while construction continues on the north side. The pedestrian walkway remains available on the south side of Steeles Avenue East beside the new retaining wall.

TTC passengers aboard buses along these routes can expect delays:

  • 53 Steeles East;
  • 353 Steeles overnight; and
  • 953 Steeles East express.

From 8 p.m. Friday, April 30 until 6 a.m. Monday, May 3, the City of Toronto closed Steeles Avenue East between Silver Star Boulevard / Old Kennedy Road and Redlea Avenue to all traffic, so that crews could get ready for opening the south-side underpass roadway. The TTC detoured buses along multiple routes throughout the weekend.

This next phase of construction and the resulting TTC delays continue “through to mid-2022”, meaning as late as until June 30, 2022.
