If Lac-Beauport and Quebec agree to better predict such events and warn residents more quickly, there was no question of raising the bridges in the short or medium term. On this point, Mr. Labrecque remains worried about the future and maintains that the works are too low.
There is no short or medium term reconstruction project for the Mélèzes, Brûlé and Simons Falls bridges in the Ministry's planning, confirms Émilie Lord, spokesperson at MTMD. These three structures provide access to the Mont-Cervin and Exalt districts where 3,000 people live.
There is also no question of raising the Chemin de l'Éperon bridge, rebuilt in 2023 at a cost of 2. $3 million.

The Éperon bridge is new this year and cost 2.3 million dollars to taxpayers.
In the latter case, Lac-Beauport had warned the Ministry that the bridge would be too low under the design plans presented to the Municipality. They didn't listen to us, Mayor Charles Brochu lamented this week.
The MTMD for its part pleads that its structure is solid and planned by considering, among other things, the flood events of the Yellow River. The flood zones used, however, have not been updated for many years, while new maps are expected by the end of 2024.
On the potential for flooding, the MTMD suggests that an enhancement may prove unnecessary if the environment of insertion of the infrastructure is located in a flood zone.
The raising of a bridge may prove non-essential, particularly if the roadway upstream or downstream is located in a flood zone.
A quote from Émilie Lord, spokesperson, Ministry of Transport and Sustainable Mobility
Ms. Lord adds that the Ministry also had to deal with the framework built from Chemin de l'Éperon to Lac-Beauport and respect the presence of residential entrances in the area.
The Ministry also denies having caused the December floods. It is imperative to consider the exceptional rains of December. The swelling of the Yellow River did not cause any damage to the structure newly constructed by the Ministry, even if the water rose near the soffit of the bridge.

The general director of Lac-Beauport, Richard Labrecque, also noticed this year a change in the MTMD's practices regarding the closure of bridges. Rather than closing the roads when the water reaches the deck, Quebec closed the bridges as soon as they reached the soffits, almost a meter lower in some cases.
Without specifying how, the Ministry cryptically confirms that it has indeed changed its practices, which are continuously evolving.
The precision of knowledge and experience which is progressing in all areas (hydraulics, structures, geotechnics, earthquakes, climate change, etc.) is also reflected in the updating of procedures, it is indicated.
< p class="StyledBodyHtmlParagraph-sc-48221190-4 hnvfyV">The recurrence of claims is also one of the elements analyzed. Public safety being an important element, the Ministry focuses on prevention, particularly when the recurrence of events in the same sector increases over a given period.
