Notice of Byron Avenue Closure

Between Sherbourne Road and Redwood Avenue

January 2023

Update: The date in this notice has been revised. The road will reopen at the end of January.

As part of the Stage 2 O-Train Light Rail Transit (LRT) project, Byron Avenue will be closed to vehicles between Sherbourne Road and Redwood Avenue.


Long-term closure, Byron Avenue, Sherbourne Road and Redwood Avenue.


The road will reopen at the end of January.


The closure of Byron Avenue is required to facilitate construction of the Cut and Cover Byron Tunnel in this area. The work zone is required to prepare the area for a future detour of Richmond Road, and includes utility relocations, construction of a temporary bridge, backfill of completed tunnel sections, and road construction once underground work is completed.

Motorists should adhere to detours, traffic control signage, posted speed limits, allow for added travel time and use extra caution when moving through active construction corridors as traffic patterns change.
Pedestrians and cyclists should use extra caution and adhere to posted signage to ensure safety.
