Right now in Montreal a tunnel to the south shore of the river is partially closed, with 2 lanes going out and 3 lanes in, and large temporary deviations on the exchanger close to it. There are major renovations coming in the next years. Now this friday I had to travel on the south shore to see family. My sister, living further north, also had to come. Normally, crossing the tunnel on a friday around 5 PM is a perfect recipe for disaster. With the tunnel partially closed, everyone thought it would take hours to cross it. My sister chose to take the long detour further east to take a ferry near Sorel. I didn't have this option, but I recently heard about the Braess paradox, and although I'm not understanding it very well, I decided to take my chances and take the tunnel. Well, it took exactly 10 minutes to cross it.
