|
Mining operations are ongoing at the Secondary Entrance and occur 24 hours a day, seven days a week. Read the construction notice for more detail.
What Work is Taking Place
- Mining excavation is ongoing east of the Secondary Entrance between Oriole Parkway and Eastbourne Avenue. This sequence includes drilling roof supports, removal of earth and coating exposed surfaces with shotcrete. Excavation east of the Secondary Entrance is expected to be completed in July 2020.
What Work is Coming Up?
- Upcoming lane reduction west of the Main Entrance on Eglinton Avenue West to facilitate weekly concrete pours. Each pour will last for approximately 12 hours. The lane will be re-open after each pour is complete. See construction activities below for details.
- Upcoming inner walls demolition at the Secondary Entrance on Thursday February 20, 2020 and will occur 24 hours a day for approximately six (6) days. Some vibration and drilling may be heard.
Mining Information
General mining activities occur in a continuous sequence, including drilling roof supports, excavation under the roof supports and spraying of concrete to finalize exposed areas underground. Within the excavation portion of the sequence, periodic removal of concrete sections of the existing tunnels is required as well as periodic chipping of temporary concrete linings. When possible, crews complete higher impact works during the day, however due to the sequence nature of the work and the engineering requirements related to ground stability and cavern integrity, sometimes noticeable activity occurs overnight.

Noise & Vibration Mitigation
Noise and vibration impacts to your building depend on your proximity to the source and how the vibrations travel through the soil and interact with the foundation and structure of your building. Crosslinx Transit Solutions has implemented several noise reductions measures on site to mitigate the impact felt by the community during mining activities. Enclosures are used to cover equipment like generators and pumps, silencers are used to reduce noise from fans, and delivery routes and times are selected to minimize disruption – just to name a few.
If you experience disruption from mining activities, please call our 24/7 phone line at 416-782-8118.

Concrete Pours
|
- Concrete pours will occur weekly over the next year.
- Concrete trucks will be staged in the existing laydown area on the north side of Eglinton Avenue and exit the site at the gate on the west end of the site.
- Some of the trucks will be required to back into the west gate of the secondary entrance due to coordination with other construction activities that will be underway during the concrete pour.

|
|
|
Lane Reduction for Concrete Pours
|
- Periodic lane reduction west of the Main Entrance for concrete pours will occur weekly over the next six months.
- Concrete trucks will be staged in Eglinton Park and travel to the Main Entrance to facilitate the pours.
|
- Approximately 12 hours for each pour
|
- Tuesday February 18, 2020 at 7 p.m.
|
|
Walls Demolition
|
- Inner walls demolition at the Secondary Entrance, between Oriole Parkway and Eastbourne Avenue.
|
- Wall demolitions will take place on a 24-hours basis
|
- Thursday February 20, 2020 – Wednesday February 26, 2020
- 24 hours
|
|
Dewatering Well Maintenance
Periodic maintenance of dewatering wells as required
|
- Periodic maintenance will be ongoing and require a short duration (1 day) enclosure around the well in the right of way.
- A compressor and occasional hydrovac truck will be used to complete the maintenance.
|
|
|
|
Monitoring Work
Equipment is installed in various locations around the station are to monitor ground movement during construction.
Read the construction notice for more detail.
|
- To install the monitoring equipment in the ground, crews move from location to location around the station area. Typically, a drilling machine is used to drill
the hole where the monitor will be installed.
- If on the sidewalk, pedestrians may need to be routed around the work zone (sidewalks stay open). If on the roadway, a short-term lane closure may be required.
|
- Readings will be taken regularly for the duration of the project.
- Installations planned to be
complete in the next few months.

Currently installations are focused east of Secondary Entrance
