It actually consists of two parallel water bridges, that lead the Mittelland Canal over the Weser.
After the Magdeburg Water Bridge, it is the second biggest aqueduct in Europe.
At the end of World War II it was destroyed by the retreating Wehrmacht in 1945.
Over the years, ships became larger and so the canal grew too small.
It is 1.2 km long and enables an approach to the Abstiegshafen.
