In the Netherlands there's one point where two highways cross with traffic lights. To solve this, they are "pushing a tunnel for the A59 underneath the A27", within 100 hours.

I mean, what?

Apparently they dig a gap in one highway, drive the concrete tunnel in that gap, and restore the highway over that new tunnel...

All these steps happen in one weekend, this weekend. This is a time lapse of the tunnel being driven into that gap, which has just finished. It's quite amazing.
