It's not great footage, being video of a video monitor recorded with a potato, but it's a quality bridge collapse with no apparent fatalities and one of the most cinematic escapes reality might provide: keep your eye on the person waiting for the train in the bottom right of the shot, next to the pillar.
Machtrans of the Russian caption:
On 09.10.2018 in the morning, there was a collapse of a CAR BRIDGE THROUGH A TRANSIB. A few more cars were miraculously managed to drive. The Russian Railways employee was born in a shirt! I almost died under this bridge! Angel keeps it!
