The famous video of Dutch Directorate-General for Public Works and Water Management (Rijkswaterstaat) building a tunnel under a highway in just one weekend.

The tunnel is only 70 meters long but it is still remarkable that it was built in the weekend of 20-22 May 2016.  It was ready to be used the next day on 23 May 2016. The tunnel is under the highway A12 towards the Arnhem direction.
