Flushing of the Rosemère's waterworks system

During the next few weeks, Rosemère will be carrying out the progressive flushing of its waterworks system, throughout the entire territory. This will be done weekdays between 7:30 a.m. and 7 p.m.

When you spot crews at work in your neighbourhood, reduce your water consumption and avoid doing laundry during the above-mentioned hours, since water pressure could be low. Furthermore, at the end of the day, check the quality of your water and if it is cloudy, turn on all cold water faucets and let the water run for a few minutes.

To know the sectors concerned, click on this link which will be updated regularly according to the progress of work on the territory.

We regret any inconvenience arising from this operation and thank you for your collaboration.

From June 2 until the end of August 2019, the Ministère des Transports will be carrying out paving work on Route 117 as well as on ramps and service roads of Highway 640. Mostly completed evening and night in order to limit the impact on the road network, these will result in partial road closures and complete closures of ramps and service roads of the highway.

  • Paving of highway ramps and service roads of Highway 640 at Route 117

Weight Restrictions ON THE Île-Ducharme Bridge

A temporary weight restriction is currently applied on the Île-Ducharme Bridge until reinforcement work is completed.

Please respect the signs in place.


Weight restrictions on the Île Bélair Bridge (R-117 – Labelle Blvd.)

The Ministry of Transport, Urban Mobility and Electrification of Transportation advises the public, truckers in particular, that weight restrictions will be implemented begining on august 10 in the Île Bélair Bridge located north of Marius-Dufresne Bridge on Route 117.

This measure is required in order to maintain the structure’s functionality. It should be noted that the condition of the bridge does not in any way compromise the safety of users.

Weight restrictions based on the type of vehicle

The following vehicles will no longer be allowed to drive over the bridge:

  • single-unit motor vehicles weighing more than 18 tons
  • double-unit motor vehicles weighing more than 26 tons
  • motor vehicles consisting of more than two units and weighing more than 34 tons.

Work on the structure is being planned. This work will seek to limit repercussions for road-users in this sector.

Between 2016 and 2018, the Québec Ministry of Transport, Urban Mobility and Electrification of Transportation will be investing a total of $4.7 billion on Québec’s road network, with more than 2,100 active work sites.

To get around more easily, call Québec511.info for information on current and upcoming roadwork. Furthermore, to ensure the safety of road-users and road workers alike, it is essential to comply with posted signs.
