I'm not making this up! I like visiting Montreal, but I don't look at the bridges, and now I won't look up! Unfortunately, if you have a lot of spontaneous failures, it doesn't bode well for earthquake capacity. Like the AECL Rusty Bucket, if things are falling apart on their own, there will be massive failure when the earthquake hits.
And Montreal is one hot earthquake zone! However, cities that are living under the Sword of Destruction, seem to be livelier. Who gives a hoot? I don't even worry about the Next Great Toronto Earthquake, since the city is doing a good job of destroying itself. :)
