The viaduct

This viaduct is one of the more important road equipment in all Belgium. It's an enormous metallic viaduct on an highway crossing the Mass / Meuse river. All internal structure is hollowed. This recording is made inside the box girder bridge, as you can walk inside the bridge as in a metallic tunnel. Trucks make enormous explosions. Infrasounds are gigantic and make effects on the human body. It was very hard to record as everything terribly vibrate, but an accomplishment. Flavien Gillié adviced me and thanks to him.
