Video Showing Tunnel Built In Three Days

Every once in a while I come across a video showing something amazing. The video below shows a 70-meter tunnel (230-feet) being built in 3 days.

According to this article:

“The impressive work was carried out by the Dutch construction company Heijmans on the A12 highway towards Arnhem in the Netherlands. 

The busy national road was shut over the weekend but was back up and running by the Monday morning.”
