If I remember correctly, there have been no ice bridges at all anywhere on the Richelieu River since 2014 or 2015. It is important to understand that there were also ice bridges in other places. I imagine that this is still a relatively new phenomenon that can have economic repercussions. As you mentioned, people who live on a shore may review their life choices in light of this new reality.
That said, there is a federal infrastructure that you would like to be able to use, the dam on the Richelieu River. What responses have you received so far about your project to transform this dam so that it can serve as a bridge?
