I'm sure a lot of detroiters will want to look at this from a standard post-apocalyptic point of view.
I am referrig to today's news about I-94 and I-96 collapse. I hope no one was seriously hurt in the car that fell from the overpass. The weather in Detroit is very similar to ours in Montreal, and it helps to bring things into perspective. A lot of cities went through the same craze of overbuilding and never thought twice about the cost of maintenance back in the day. We have had a growing number of these incidents in the past 5 years to a point where the biggest interchange in the city will be demolished and rebuilt as a ditchlike freeway instead of an elevated one. Here's a report about one overpass collapse a couple of years ago;

The earlier collapse they mention happened while the overpass was being built ten years a go. The contractors had let the structure unhinged. A concrete span was installed over the highway on a friday afternoon without proper structural support and crushed a passing car killing 3 people headed for a formula 1 race in the city. Everytime I drive over and under the Turcot overpasses I wonder if I will make it. It is in a really bad state and is right next to downtown. The nightmare of jackhammer and cranes for the next ten years is daunting. A 42 year old structure eroded by tons of ice, water and salt. The steel structure is corroded and pushes huge chunks of concrete outward.

This is the Turcot interchange slated for demolition and rebuilding[[?)
