All in a weekend's work

"In May 2016 officials with Rijkswaterstaat, the infrastructure management agency in the Netherlands, installed a tunnel beneath highway A12 near Ede. The tunnel, which weighs 3,600 tons and measures 230 feet long was installed below the highway in just one weekend by digging away the highway and inserting the new tunnel."
This would have taken 10 years in Chicago, and then, at the end of 10 years, "improvements" would be required.

Very cool. Like a modern version of the Amish doing a barn raise.
