I don't understand what's special about it. Another strange thing, the city nearby wasn't even mentioned and I had no clue where it even was, Nijkerk or Harderwijk. Apparently it's near Harderwijk and I even passed it by bicycle a few years ago. The view is nice from both sides, but I never considered the tunnel to be interesting. I guess I am the wrong kind of nerd, not one for tunnels :) In normal conversation we just call it a tunnel, just like this traintunnel near Kampen: https://www.openstreetmap.org/way/426003807 https://www.openstreetmap.org/way/426003807
