Project description

The objective of the project is to complete the design and construction of the realigned Greenbank Road and Southwest Transitway Extension between Marketplace Avenue/ Chapman Mills Drive in the north and Barnsdale Road in the south including a new 610 mm diameter transmission watermain along the realigned Greenbank Road from Market Place to the south side of the Jock River.

The project will include the design of a new 4-lane arterial roadway with 2-lane segregated median Bus Rapid Transit and facilities for pedestrians and cyclists along the corridor. The project also includes a new bridge over the Jock River, a Park and Ride facility near the southern terminus of the future transitway corridor, and design of new watermains and sewers.

The project will be guided by the work completed as part of past Environmental Assessment (EA) studies, which each involved an extensive study process and included consultation with the public. In advance of the preliminary design, an updated functional design was developed to reflect newer design standards developed since the following various EAs were completed:

  • Greenbank Road (from Malvern Drive to Cambrian Road) Class EA Study (December 2006);
  • Southwest Transitway Extension (from Strandherd Drive to Cambrian Road) Individual EA Study (December 2006);
  • Realigned Greenbank Road and Southwest Transitway Extension (Cambrian Road to Barnsdale Road) EA Study (July 2014);
  • Chapman Mills Drive Extension (Longfields Drive to Strandherd Drive) and Bus Rapid Transit Corridor (Greenbank Road to Borrisokane Road) EA Study (November 2016); and
  • Greenbank Watermain EA (October 2017).

Land acquisitions requirements vary along the corridor. The exact property requirements will be determined during detailed design in coordination with ongoing development.

Project timing

A general summary of the estimated design timelines are as follows:

  • Winter 2020/2021 – Consultant selection and updated functional design start
  • Late spring/summer 2021 – First public information session
  • Spring/fall 2021 – Field investigations
  • Winter 2024 – Finalize preliminary Design
  • Fall 2025 – Finalize detailed design
  • 2024-2025 – Property acquisition
  • 2026 - Start of phased construction

The above timelines are estimated and may change as the project progresses.

The full construction timelines are yet to be determined and will be dependent on future budget approval and coordination with other infrastructure projects across the City. Currently, phased construction is planned to start in 2026 and will depend on future Council budget deliberations and transit affordability considerations. The construction phase of this project will occur over multiple years.

The City is completing an update of the Transportation Master Plan which is currently scheduled for completion in 2025. As part of this work, the City will be reviewing the prioritization and timing of future infrastructure projects, including the re-alignment of Greenbank Road and Southwest Transitway Extension. Based on this review, the timing of future projects may be adjusted based on network needs and available funding.

Public engagement

Stay tuned on this webpage and our social media pages for information about our public information sessions and how you can contribute feedback to the project!

Our first public information session was held on June 24, 2021 to present the updated functional design drawings to the public. As part of the online engagement session between June 24 and July 8, residents were to review the design, ask questions and provide comment on the proposed works. Presentation materials are available for review below.

Additional public information sessions will be scheduled and held throughout the design process. Residents will be notified of these events.
