Metrolinx and its contractors continue upgrading GO Transit’s Barrie line as part of the GO Expansion Program.

As part of the GO Expansion construction at Maple GO Station, Metrolinx contractors are installing a bridge girder at the Major Mackenzie rail bridge to support the bridge structure and smaller beams.

Crews work from 7 a.m. until 5 p.m. each day. Nearby residents and business people can expect to hear noise resulting from construction activities and while crews use a crane. The Region of York is restricting traffic

• on Major Mackenzie Drive between Keele and Hill streets

in the City of Vaughan to just one lane from Monday, October 21 until Friday, October 25.

The Region is also closing the same section of Major Mackenzie to all traffic Saturday, October 26 and Sunday, October 27.

To accommodate work on the project, GO is cancelling service along its Barrie line late Friday, October 25 and all day Saturday, October 26 and Sunday, October 27. York Region Transit is also detouring its buses late Friday and all day Saturday.

Metrolinx and GO plan to accommodate more passengers and increase service along the Barrie line, as part of their GO Expansion Program (formerly “regional express rail”).
