This month, crews start relocating various utilities to build the extraction and launch shafts at Eglinton Avenue West and Allen Road. They’ll be building an extraction shaft for the tunnel-boring machines west of Eglinton West Station and a launch shaft east of the station.
Tunneling requires contractors to build extraction and launch shafts before the tunnel-boring machines can get to work. The launch shaft is where the machines begin their underground journey. The extraction shaft is where crews will remove the machines after they’ve completed a section of the tunnel.
For this project, the TBMs start tunnelling eastward from their original launch site near Black Creek Drive. After they arrive near Allen Road / Eglinton West Station, crews will remove the machines from the extraction shaft and then reassemble them east of the station, so that the machines can start a second tunneling drive eastwards towards Yonge Street. Eventually, they’ll be building a link to the 1 Yonge - University - Spadina subway and a new LRT station the subway between the extraction and launch sites.
Before they can build they shafts, crews have to move utilities safely out of the way. Depending on site conditions, they may relocate gas, hydro, water mains, sewers, street lighting and telephone lines so they can install the extraction and launch shafts.
At first, they’ll be working on the north side of Eglinton Avenue West from west of Atlas Avenue to east of William R. Allen Road. Barriers will be separate the work zone from the traffic.
Stage 1 work reduces traffic to just one lane in each direction near the construction zone. Crews will be working on the north and centre lanes of Eglinton West while diverting traffic to the south side of the street.
They’ll also block access to Park Hill Road from Eglinton Avenue West for about a month. During this first stage of the project, they’ll also start preparing the site for future long-term construction.
Take care if you’re traveling in the area. Pedestrian walkways remain open, but watch for any signs advising you to walk around the construction zone. “Paid-duty” Toronto Police Service officers may be directing traffic at intersections for various construction activities.
The work requires the TTC to relocate both east- and westbound TTC stops for the safety of passengers. Watch for signs guiding you to the nearest available bus stop.
The City of Toronto has amended its Noise Control By-Law to permit contractors on transit projects to work from 7 a.m. until 11 p.m., seven days a week, if necessary. However, the contractors will not always work during these longer hours, but may do so if necessary.
Passengers riding TTC buses operating along the 32 Eglinton West, 63 Ossington and 109 Ranee routes should expect delays.
