This work will take place in at the same time as work on the southbound overpass, which is aimed at modernizing the railway infrastructure.

Mitigation measures:

• This work will generate noise and dust. Environmental experts will monitor noise and air quality to ensure that project criteria are met. Mitigation measures will be implemented to limit the impact.
• Overnight and weekend work may take place occasionally. The night time slot is necessary for certain types of work near the railway tracks. Noisy activities will be concentrated in the daytime and evening when possible.
• Access will be maintained for buildings in the vicinity of the work.
• Flaggers and appropriate signage will be present to facilitate traffic flow.

* Concentrated noisy activity in the daytime and evenings.
