Impacts

  • Nearby residents may experience some noise associated with these activities
  • Sound and air monitoring technology will be utilized to ensure that noise levels do not exceed Metrolinx’s construction noise criteria for residential work
  • Vibration monitors will be used to ensure vibration remains below acceptable levels
  • Lights will be pointed towards the bridge to minimize any light pollution to the area
  • Eastbound access to Vaughan City Hall will be closed; westbound access will remain open 
  • Local access will be maintained 
  • This work will not impact GO service at Maple GO or along the Barrie line 

This project is being led by Metrolinx. For more information visit Metrolink's GO Expansion project.
