Tunnel under the Bridge
This tunnel is the second floor under the train bridge " Grandfey ". It was built around years 1920-1930. This way is accessible only for cycles and pedestrians. There is a beautiful scenic view on the Sarine river and the Schiffenen lake in Canton Fribourg, Switzerland. When a train pass above, you can feel the vibrations and hear the power of a train.
