A Transportation Environmental Study Report (TESR) Addendum has been prepared to document changes to the recommended plan for improvements to Highway 400 from 1 km south of Highway 89 to the Junction of Highway 11 outlined in the 2004 TESR. The TESR Addendum includes a discussion on the need for the changes to the 2004 TESR, the generation, assessment and evaluation of alternatives, the recommended plan, a summary of environmental issues and potential mitigation measures, a summary of consultation undertaken, and commitments to be carried out during future design and construction. The TESR Addendum is available for a 30-day review period commencing Thursday November 9, 2017 and ending Friday December 8, 2017 at the locations listed on the Notice of TESR Addendum Submission.

AECOM (formerly URS Canada Inc.) has been retained by the Ontario Ministry of Transportation (MTO) to undertake a Preliminary Design Study Update to examine the nature of improvements required to address traffic operations, capacity, and safety needs along a 30 km section of Highway 400 from 1 km south of Highway 89 to the junction at Highway 11. Reasonable alternatives to address the required improvements will be developed and evaluated leading to the selection of a preferred alternative(s). The project limits are located within the Town of Innisfil, City of Barrie, and the Township of Springwater within Simcoe County.

In addition to this study, MTO is undertaking a Preliminary Design study for the advanced replacement of the following four structures along this section of the Highway 400 corridor:

  • 4th Line (Churchill Sideroad) Bridge
  • 6th Line Bridge
  • Barrie Collingwood Railway Bridge
  • 10th Line (McKay Road) Bridge

These structures will be advanced as part of a separate study and designed to incorporate the recommendations of the overall Highway 400 corridor improvement study.

This study is following the approved planning process for a Group ‘B’ project under the MTO Class Environmental Assessment (EA) for Provincial Transportation Facilities (2000).
