Rethe Bridge

When two large ships passed through the river crossing of the Rethe bridge or if trains used the bridge up to 40 times a day, for drivers of vehicles this meant: Switch off the engine and wait. Now this is a thing of the past. Because the new Rethe bridge built by HOCHTIEF separates rail and road traffic. The unique structure can proudly claim to be "Europe's largest bascule bridge for combined road and rail traffic".
