Notice of Recurring Temporary Road Closures Byron Avenue

As part of the Stage 2 O-Train Light Rail Transit (LRT) project’s Cut & Cover Tunnel construction, sections of Byron Avenue will be temporarily closed for the pouring of concrete and deliveries. Each pour requires 10 to 15 hours to complete as well as to stage delivery vehicles, cranes, and concrete trucks. Please note that concrete pours must be performed continuously until completed to ensure the quality of the concrete.
In addition, station construction is underway at New Orchard and Sherbourne Stations until winter 2024-2025. Temporary closures on Byron, near those two stations, will also be periodically required for stations work.
Byron Avenue continues to require *daylong closures of approximately one block to allow for work staging as the Cut and Cover Tunnel progresses. The sidewalk on the south side of Byron Avenue will remain open and accessible. Traffic will be detoured around the established work zone. Flag persons will be onsite, as required. Night work will occur subject to a valid noise by-law exemption, in addition to daytime activities on weekdays and weekends.
*Cranes and equipment will be demobilized at the end of each day, reopening Byron Avenue to general traffic.
Concrete works are ongoing and anticipated weekly throughout 2024. Road closures begin with the mobilization of the delivery vehicles, cranes, and concrete trucks as well as the temporary road closure. Please note that KEV is targeting 10:00 p.m. completion time (5:00 p.m. on Sundays) per occurrence, however, as mentioned each pour will proceed until completed and may proceed into the night.
A crane, as well as several delivery vehicles and concrete trucks, will be staged to accommodate the work on the Byron Tunnel. The size of the equipment and nature of the operations require daylong closure of a section of Byron Avenue.
*Construction vehicles are not permitted on residential streets and flaggers are utilized to ensure vehicles adhere to this City and Project requirement.
Work will occur via Byron Avenue between New Orchard and Sherbourne Avenues.
7:00 a.m. to 10:00 p.m. Monday to Saturday and 9:00 a.m. to 5:00 p.m. on Sunday. Note that concrete pours may extend beyond the end time.

Pedestrian mobility will be maintained using the south sidewalk on Byron Avenue.
Residents can expect noise from delivery vehicles, concrete trucks, and cranes.
