Bridge Rehabilitation on Downsview Avenue and Gordon MacKay Road over Black Creek

Contract: 20ECS-TI-12BE

Actual Start Date: August 2020 Expected End Date: May 2021*

*Timeline is subject to change.

The City of Toronto is planning to rehabilitate two bridges over Black Creek on Downsview Avenue and Gordon MacKay Road near Jane Street and the 401.

Due to the delay in construction commencement and additional work to promote safety and longevity of the bridge structure, the Gordon MacKay bridge work has been extended and work is now expected to be completed in February 2021. Meanwhile, work on Downsview Bridge is expected to be completed by December 2020. The delay on the individual bridge work is not expected to have an impact on the overall end date of the project, which is still scheduled for May 2021.

The City's contractor is working diligently to complete the remainder of the project. We thank you for your patience while this work takes place.
