This is NOT a bridge or a tunnel! This is a beerpipe. Before the golden age there was a lot of beer comming from Germany while the water did not last very long. Beerbrewers brought their beer to the beautifull city of Hoorn. After it arrived in the harbor it was transported to the hinterland through this beerpipe. Do you want to know more?
