My apologies for the Twitter link. Appears to have happened around 1:30 EDT, judging from the timestamp in the video. Seems unsurprising that Amerikkkan infrastructure is in this dire of a state (at the cost of innocent people's lives, as usual), but I'd still love to know what the hell happened here. Hopefully the early hour meant that more people weren't harmed.

At the very least, it doesn't sound like there were very many vehicles on the bridge. Imagine if this happened during rush hour.
