Grenzübergang - Border Crossing
It may not exactly look like one, but this is a border crossing. On this side of that little bridge is Germany, on the (not so) far side are the Netherlands. The only indication that you enter an other country is the board with the name of that little town. In the Netherlands those sign boards are blue with white letters, while in Germany they are orange with black letters.
Even during the Covid 19 crisis the border with the Netherlands remains one of the few you can cross without fuss.
