On a hiking tour near Klammstein, I come across an interesting place. Below Klammstein Castle (Burg Klammstein) there is a tunnel for bikers and walkers only. The structure is part of a cycle route along the Gastein Valley (Gasteinertal).
I like the idea to offer a separate tunnel for bikers and walkers inside a rock so all of them are able to use the cycle route in a save way without the noise and fumes of cars. Do you know similar projects in your region?
