The emergency inspection of 605 overpasses across the province ordered by the Transport minister revealed 47 structures that required immediate repairs.
Spokesperson Sarah Bensadoun says the Ministry will be paying a lot more attention to the weather from now on.
She says freeze-thaw cycles like those recently felt over Montreal can wreak havoc on concrete structures.
"The ministry is going to review some of its protocols and we are going to integrate weather alerts," she confirmed.
"As soon as there is a cycle of warm and cold weather, we are going to automatically verify a series of structures and will secure them if necessary."
The spokesperson explained that the 47 overpasses all showed risks of delamination, which means concrete on the surface could fall off at any moment.
Thus, workers were tasked to chip away any blocks that were loose in order to prevent any incidents.
In Montreal, 112 structures were evaluated and 11 required an intervention.
The Turcot interchange accounted nearly half of the repairs in the area. Five of its lanes were targeted by workers, who chipped away blocks of concrete they suspected could fall loose.
Despite the urgent repairs, Bensadoun says everything is safe now.
"I want to make sure this is clear: Traffic would not be permitted if there was any kind of danger."
The emergency inspections were ordered by Transport Minister Sylvain Gaudreault after a piece of a concrete fell from Henri-Boruassa overpass onto Autoroute-40 last Monday.
