The warm weather has finally arrived, and with it, the opening of windows in our homes.  This means that some people may hear noises (the normal sounds associated with any major job site) from the new Champlain Bridge corridor project. 

Major traffic disruption on Nuns’ Island on the weekend of June 3–5

Demolition of the Nuns’ Island Boulevard overpass structure between exits 57-S and 57-N is set for June 3–5, following preparation work a few days before. This will cause major disruptions on Nuns’ Island Boulevard.

Unfortunately, we are forced to execute this noisy work during evenings and nights because of the major vehicle congestion it would cause if it were done in the daytime. Our Environment team will be on hand to ensure compliance with environmental requirements. See the list of suggested detour routes.

Also, as of the week of May 30 and for the upcoming year, one of the two southbound lanes on Hwy 10 East  (Bonaventure) will be changed to a northbound lane at Pointe Nord on Nuns’ Island. This change is due to major work planned this summer in the Gaétan-Laberge sector, and it could cause delays for drivers coming from downtown.

Current and upcoming work on the Nuns’ Island Bridge

Construction of the new Nuns’ Island Bridge is moving right along. We will be continuing our pile caisson drilling and concreting work. We will also be drilling from a barge in the channel. Lastly, construction has resumed on the Nuns’ Island side, near the SAX condos.

Current and upcoming work on the west approach

Prefabrication of the concrete footings began last December and will continue at the four work stations (the white tents), which will ultimately assemble a structure comprising a footing with two pile segments, capped with a work platform.

These structures will be transported and installed on the riverbed thanks to an industrial catamaran, a blue vessel identified as SARENS. Designed to navigate in the river’s strong currents, the catamaran will begin its operations in June, after it has been taken out for some routine jaunts to assess its performance in the current.

For many weeks now, ongoing marine excavations have been laying the groundwork for the upcoming installation of the footing and pile combos, which stand a total of 14 m in height.

Furthermore, building of the assembling platform for the steel superstructure is moving right along, as is the preparation work for the marine transportation of heavy parts. You will be seeing an increase in nautical traffic this summer, which is why we urge you to always proceed with caution.

Noise and air quality monitoring

Our Environment team is present at the job site every day to ensure that we comply with the noise management and air quality standards in force.

Watering of the job site as needed and while the works are underway will make it possible to keep the dust to a minimum. There are currently  four air quality monitoring stations in the Verdun and Sud-Ouest boroughs.

As regards noise management, SSL may not exceed over 75 decibels during daytime activities. At night, SSL may not exceed the neighbourhood’s ambient noise level by more than 5 decibels. Exceptionally, some noisier activities prior to the demolition of the LaSalle, Gibbons and Wellington overpasses may be carried out in the evening, given that their performance during the day would generate too much traffic congestion. We must, for all such works, not only receive the approval of the competent authorities but also keep the residents of the affected zones informed, as we are doing with this notice.

Schedule of the works

The majority of our activities are carried out on weekdays, from 7:00 a.m. (with teams arriving at the job site around 6:30 a.m.) to 7:00 p.m. Occasionally, the works will continue over the weekend, during the same hours.  Some works may at times be performed in the evening or at night.  Given that noise criteria are stricter at night, these activities are usually ones that are not overly noisy.
