"The new two-span bridge, with three lanes in each direction, a shoulder wide enough for buses and a multipurpose path for pedestrians and cyclists, will be built just to the north of the current bridge..." https://montrealgazette.com/news/local-news/construction-is-underway-on-the-new-ile-aux-tourtes-bridge
It's always nice to see when another city doesn't Vancouverize its bridges.

At least the old ...Tourtes_Bridge was designed to have 6 lanes, but the new bridge will be able to accomodate 8 lanes. Thus, the 4th lane each way will be for buses & potentially other HOV. Unlike in Vancouver, no 4th lane each way is allowed, even though that would allow for better efficiency with express bus & BRT. Apparently in Vancouver, its better to cram everything into inept & narrow bridges. Indeed, Vancouver is the epitome of bottleneck planning.
