Scope of Work

The Highway 401/Elgin Road Bridge and Interchange was originally constructed in 1957. The bridge has been identified for replacement to address operational needs and accommodate the future widening of Highway 401 to an eight lane cross section (widening of Highway 401 is not included in the current project).

In 2016, MTO completed the Class Environmental Assessment and Preliminary Design for the interchange improvements. As documented in the Transportation Environmental Study Report (January 2016) the project includes:

  • Replacement of the Elgin Road bridge and interchange ramps in the same location as the existing

  • Full closure of Elgin Road at Highway 401 for up to a maximum of six months in 2019

  • A signed detour route will be place during the Elgin Road closure

The Detailed Design process will build upon the Preliminary Design. A Design and Construction Report will be prepared to document the final design plan and environmental impacts and mitigation measures to be implemented during construction. As part of Detail Design, the project team will:

  • Finalize a traffic management plan which includes identifying an Elgin Road detour route

  • Confirm anticipated impacts to the surrounding environment and develop mitigation measures for construction

  • Obtain required permits for construction (e.g. noise by-law exemption)

This project is being completed as a Design-Build project.
