Study Overview & Background

Study Overview

AECOM has been retained by the Ontario Ministry of Transportation (MTO) to undertake a Detail Design and Class Environmental Assessment Study for the structural (bridge and culvert) rehabilitation, pavement rehabilitation, foundation remediation and interchange reconfiguration work along Highway 410, from Eglinton Avenue to Mayfield Road.

Contract 2 (G.W.P. 2369-15-00) is currently being undertaken and is following the approved planning process for a Group ‘B’ project under the MTO’s Class Environmental Assessment for Provincial Transportation Facilities (2000). The scope of work will include the following:

  • Construction of a sub-collector system along Highway 410 between Derry Road and Courtneypark Drive;
  • Construction of new N-E/W and E/W-N ramps at the Courtneypark Drive Interchange;
  • Widening and Rehabilitation of Courtneypark Drive Bridge;
  • Widening of Steeles Avenue Superstructure;
  • Rehabilitation of Steeles Avenue Bridge; 
  • Culvert rehabilitation;
  • Culvert extensions; and,

Implementation of Advanced Traffic Management Systems (ATMS) improvements from Highway 401 to north of Courtneypark Drive.

    A Design and Construction Report (DCR) will be prepared to document the study process, design details, environmental impacts and mitigation measures, and the consultation undertaken throughout the project. The DCR will be made available for a 30-day review period. The DCR review period will be advertised in local newspapers, this project website, and mailed to those on the project contact list.

    To obtain additional information, provide comments, or to be added onto the project mailing list, please contact the Project Team.

    Study Background

    Preliminary Design Study – Highway 410 from Eglington Avenue to Queen Street (W.O. 00-23020) – 2010

    A Preliminary Design Study (W.O. 00-23020) was undertaken previously and a Transportation Environmental Study Report (TESR) was prepared for this segment of Highway 410 from Eglington Avenue to Queen Street and issued in January 2010. The TESR underwent minor amendments and was re-circulated in August 2010 to affected parties. The TESR documented possible improvements to this section of Highway 410 in both northbound and southbound directions. The improvements carried forward included the widening of Highway 410 from a 6 lane to a 10 lane cross-section by the addition of one High Occupancy Vehicle (HOV) and one General Purpose Lane (GPL) in each direction.

    Detail Design Study – Highway 410 Widening from South of Highway 401 Northerly to Queen Street (G.W.P. 2144-07-00) – 2013

    In July 2011 the project (Highway 410 Widening from South of Highway 401 Northerly to Queen Street) proceeded to Detail Design (G.W.P. 2144-07-00). A Detail Design study for the project was undertaken, a Public Information Centre (PIC) was held on December 11, 2013, and the final design was completed and documented in a Design and Constriction Report (DCR) which was made available for a 30-day public review period (February 19, 2014 to March 20, 2014).

    The Highway 410 Widening from South of Highway 401 Northerly to Queen Street project proceed to construction in 2014, and is anticipated to be completed in 2018.

    Detail Design Study – Highway 410 Improvements from Eglinton Avenue to Mayfield Road (G.W.P.: 2042-13-00, G.W.P.: 2381-15-00) – 2017 – 2019

    In Spring 2017, MTO announced commencement of detail design works for the structural (bridge and culvert) rehabilitation, pavement rehabilitation, and foundation remediation work along Highway 410, from Eglinton Avenue northerly to Mayfield Road. The project works are currently separated into two construction contracts (contracts are subject to change pending funding availability and receipt of all required approvals).

    The project limits are located within the City of Brampton, City of Mississauga and the Regional Municipality of Peel.  These project works are following the approved planning process for a Group ‘C’ project under the MTO Class Environmental Assessment for Provincial Transportation Facilities (2000).

    The project work includes:

    Contract 1 (G.W.P. 2042-13-00):

    • Rehabilitation of Bovaird Drive Bridge (Site 24-469/1&2);
    • Rehabilitation of Vodden Street Bridge (Site 24-475);
    • Localized concrete pavement repairs (from Bovaird Drive to Mayfield Road);
    • Rehabilitation of ramps and crossing roads within the MTO’s right-of-way (ROW) from Bovaird Drive to Mayfield Road; and,
    • Removal, repaving, and pavement markings on Countryside Drive in the City of Brampton.

    Contract 4 (G.W.P. 2381-15-00):

    • Rehabilitation of Derry Road Bridge (Site 24-495); and,
    • Culvert rehabilitation (Site 24-577/C).
    • Retained Soil System (RSS) Wall remediation at:
      • Sandalwood Parkway (Site 24-739);
      • Mayfield Road (Site 24-738); and,
      • Bovaird Drive to Mall Access (Site 24-741).

    Key Plan

    Key Plan Map

    An Environmental Screening Document (ESD) was prepared for Contract 1 (G.W.P. 2042-13-00) and will be prepared for Contract 4 (G.W.P. 2381-15-00) to document the study process, design details, consultation undertaken during the study, and potential environmental issues and mitigation measures. The ESD will not be made available for review and comment, but can be made available to interested stakeholders upon request.
