A weird substance finds its way into a tunnel, wreaking havoc on the roads


What the ...


This is not what you would expect when going for a drive through a tunnel.

But thanks to someone's dash cam, we get to witness this bizarre phenomenon. Did snow somehow get in there? Did a fire truck rupture and its foam burst everywhere? Did the marshmallow man blow up?


Apparently, none of those. RoadCams says the weirdness was caused by a malfunction in the tunnel's venting system. I suppose it could have been worse, under the thought that something else could have gotten into the tunnel. No word on where this happened; We're just glad it didn't happen to us on the road.
