Start of icebreaking operations on the Châteauguay River
Published on 12 March 2021
Following the rise in temperature recorded over recent days and the start of ice melting, icebreaking operations will be launched from Monday, March 15 on the Châteauguay River.
From next Monday, workers from the Direction des travaux publics will focus on working below de la Sauvagine bridge to clear the mass of ice accumulated to allow the Canadian Coast Guard hovercraft to pass through, which is scheduled on Tuesday, March 16. It will clear a way through the ice up to des Adirondacks bridge with the aim of increasing the effects of currents and waves to make it easier to break the ice.
Some 24 to 48 hours later, on Wednesday or Thursday, it will be the turn of the amphibious excavator, also known as the “frog”, to break the ice cover on the river. The operations will mainly take place on the portion between de la Sauvagine and Arthur-Laberge bridges to reduce the risk of flooding that comes with the spring thaw.
To ensure everyone’s safety, the municipal authorities would like to remind residents not to go near the river when the hovercraft or amphibious excavator are present due to potential ice movements.
No problems reported
The precise dates on which the hovercraft or amphibious excavator will pass through may vary depending on weather conditions. They are used in the region as a preventative measure. All data collected to date shows that the ice-melting flows recorded are not problematic and do not present any flooding risk.
