What is it with crumbling overpasses in Canada? I thought we denizens of the Lower 48 had the decaying infrastructure. I'm glad those in the X1 weren't hurt, and thankfully my family were fine after a chunk of concrete fell from an overpass onto our Acura near Barrie, Ontario in 2012. The authorities handled our situation well, and eventually compensated us in full.
For several months after this, I was constantly looking upward when driving under overpasses, especially those over I-95 in Chester, Pennsylvania.
