In the unlikely event that this bridge were to suddenly collapse, which Montreal-adjacent island’s residents would be cut off from the rest of society?
UPDATE: Wow, got dozens of guesses on this one, most of which were right or almost right without giving the name of the island.
It is, indeed, Île Verte, a tiny island with two streets that forms part of les Îles Laval just east of Île Bizard. The bridge connects it to Île Bigras, which is more known for its commuter train station.
Île Verte isn’t labelled on Google Maps (which is why most people described it without naming it). It does show up on Mapquest though. Take that, Google!
