Notice how I dispensed with the whole "
Great Canadian..." (bothered me).
Anyhow, I thought it would be a cool topic for a thread. We will start with (what else) a little Montreal (one of the world capitals of underground cityscapes), and the Ville Marie Expressway (Tunnel), arguably Canada's only underground urban highway of significant length (I suppose some could say that Decarie is another, as it is below grade but for the most part, not a tunnel, although parts of it are covered). The Ville-Marie Tunnel may be falling apart, but few things scream "big city" as much as driving through it: diving under the skyscrapers, to emerge 5 minutes later on the other side, and then another, shorter (Viger) tunnel.
