Massive commercial passing Sint-Servaasbrug
A moveable part of the Sint-Servaasbrug is constructed on top of the channel that is especially intended for use by commercial ships. This video shows a large commercial cruising upstream and passing underneath the lifted bridge. Under normal circumstances, being the river not in spate, the air-draught is around 6 meters (20 feet). When the movable part is lifted some 2 meters (almost 7 feet) is added, creating a clearance of around 8 meters (26,5 feet). If necessary big commercials ships are often capable of lowering their wheelhouse, sometimes even with the head of the person in control protruding!, thus increasing the possibility of passing low (low for them, that is) bridges.
