Major scope of work items for this project include:

  • New rail grade separation structure between north-south GO Barrie Rail corridor and east-west CP Rail corridor;
  • New retaining walls forming the approaches of the grade separation structure topped with noise reduction walls to minimize impacts on the community;
  • A temporary diversion track to enable construction of a new two-track elevated guideway;
  • Modification of an existing at-grade road crossing at Wallace Avenue to become a road under rail grade separation;
  • Replacement of the Bloor Street West Bridge; and
  • Construction staging in an active rail corridor with limited access points; and

LEA is thrilled to be a part of the team, and we look forward to working together with our partners to build a stronger, more accessible connection on the GO transit line. For more information on the project, please check out the announcement from Infrastructure Ontario.
