What is Happening?
As part of improvements being made for Aurora GO, Metrolinx crews will be conducting nighttime signals work within the rail corridor (see Figure 1). This work will include excavations.
Crews will begin this work north of Wellington Street first, before moving south of Wellington upon completion of the north work.
What to expect
- Construction lighting may be visible from the work site.
- Where possible, lights from equipment will be positioned away from residential homes to keep light pollution levels low.
- Trucks and construction equipment may generate dust during construction.
- Crews will take precautions to monitor and reduce dust.
- Increased presence of construction vehicles and equipment can be expected in the work area.
- Work may be delayed or rescheduled due to weather or unforeseen circumstances.
- Trucks will stage inside the work site and will not stage outside of the site boundaries
Traffic Changes
- No disruptions to traffic are anticipated.
Pedestrian Access
- All pedestrian sidewalks will remain open throughout the work.
Noise and Vibration
- Residences and businesses in the area may experience noise and vibration caused by construction equipment related to this work.
- Crews will take measures to minimize disruptions to the surrounding area wherever possible.
- To minimize noise impacts on the community, noise and vibration monitoring equipment will be installed prior to construction. These devices will help to detect exceedances early to proactively conduct corrective actions as needed while crews work.
- Trucks accessing the site will be equipped with broadband backup alarms, which emit a less disruptive sound compared to traditional beeping backup alarms.
Transit Service
- There is no anticipated impact to transit services.
