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 continues between Eastbourne Avenue and Lascelles Boulevard. This sequence includes drilling roof supports, removal of earth and coating exposed surfaces with shotcrete. Mining excavation is expected to be complete in July 2020.
- Approximately three concrete pours take place every week lasting 12 – 18 hours each. The concrete forms the station structure below grade. Some pours require temporary use of the westbound curb lane at Main Entrance. The lane will re-open after each pour is complete.
What Work is Coming Up?
- As early as Wednesday, May 6, 2020 crews will perform the next concrete pour at the Main Entrance, temporarily occupying the westbound curb lane.
- Demolition of the inner station walls will continue as early as Thursday April 30, 2020 and will occur 24 hours a day for approximately three (3) days. Nearby properties may experience noise and/or vibration.
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.
