Oops... it did it again!

This time, according to this article, it looks like the expansion joint separated on the eastern side of the bridge.
Holy cow.
As they clarify later on, it's not a bridge flaw. It's the use of temporary expansion joints awaiting the final asphalt layer.

^ There was a lot of misinformation about this incident. Even the CBC article incorrectly stated that the bridge was "closed" because of this. It wasn't. The westbound lanes were closed temporarily, but alternating flow was permitted on the eastbound lane of the bridge. Given the time of day that the incident occurred, and the traffic volumes in the area in general, there probably wasn't even much of a travel delay caused by this work.
I'm driving up to Northwestern Ontario the week after this one for work. I'm pretty eager to see the updated bridge. It's been since 2015 that I was last in the area, so obviously a lot of work has transpired since that time.
