The Netherlands is also well known for their ecopassages over highways (also known as ecoducts), according to Wikipedia there are 66 eco passages in the Netherlands as of 2015 [0]. There are some nice pictures of them in the wiki article as well.

One of those ecoducts [0] has a millitary shooting range on one side, which I always found quite funny. It is of-course quite safe since shooting exercises are rare. (Ignoring the fact that for some time, our soldiers would practice by shouting 'pang pang' ('bang bang' translated) [1] because ammo was too expensive)

More remarkable than ecopassages are the underpasses built specifically for canals or major rivers. There are a few of these on the way from Den Haag to Utrecht that are pretty mind-boggling. It's also interesting to see cargo shipping going OVER the highway.

It was very noticeable to me in Dutch cities that there is wildlife.
