Gee, I no sooner post about highway overpasses collapsing that I get this news. Hopefully the two are unrelated, though it is very ironic that early reports suggest the problem may be related to the new bicycle lane being built along De Maisonneuve. What a country! Good job by Ed Hawko of Blork Blog in getting the story on the net in a hurry!

Seems it is serious enough that the Metro (subway) may even stay closed for the weekend. Story here.
