Queen Street Bridge Rehabilitation Project

About the Project
The Town of Newmarket is undertaking a construction project that will see the replacement of the Queen Street bridge above the train tracks (located between Main Street and Prospect Street). See map below for more information. This work is needed after regulatory structural inspections of the bridge, determined that the bridge superstructure required a replacement. Work on the bridge will ensure it continues to be safe for all to use while connecting the community to the heart of Newmarket.

This work is being done in conjunction with Metrolinx and Bell Canada in order to support the Future GO Transit Expansion Plan and the Electrification of the train tracks. This work is expected to take place in two phases.

Phase 1: Bell Canada utility work

• Directional drilling for the telecommunication conduit (2023)
• Splicing and reconfiguration of telecommunication cables (2024)

Phase 2: Town of Newmarket's Infrastructure improvements to the Queen Street Bridge (March 2025-December 2025 - subject to completion of Bell Canada's works)

________________________________________________________________________________

The Town of Newmarket would like to inform you that the overnight work related to the Queen Street Rehabilitation Project has been rescheduled tentatively to May 5th, 2025 and will no longer commence on April 28^th as previously communicated to you.

Please note that this new start date is tentative and could be subject to change as we continue to coordinate the work with Metrolinx. We will keep you updated if any further changes occur.

As a reminder, this overnight work will involve the removal of the bridge girders directly above the Metrolinx tracks. Due to active rail operations, this work must be conducted outside of regular train service hours to ensure the safety of workers, the public, and transit operations.

We greatly appreciate your patience and understanding as we carry out this critical infrastructure work. The completed bridge will improve safety, accessibility, and long-term maintenance, and will align with Metrolinx’s plans for railway expansion and electrification.
