Work Hours

Work on this project will take place 24 hours a day, 7 days a week. Excavation activities and heavy breaking will be carried out at various times throughout the day. All concrete breaking activities will occur between 7 a.m. and 11 p.m. Concrete breaking work is the most disruptive and will typically last the first one to two days for each phase of the construction. Around-the-clock work during rail installation by TTC is required to preserve the integrity and quality of new rail and concrete. Overnight rail work by TTC may consist of moving new rail into position, rail installation and rail welding / grinding.
