Magdeburg Water Bridge
Magdeburg Water Bridge (Wasserstraßenkreuz Magdeburg)  is the Europe's Largest Water Bridges 
Six years, 500 million euros, 918 meters long…….now this is engineering!

This is a channel-bridge over the River Elbe and joins the former East and West Germany, as part of the unification project. It is located in the city of Magdeburg, near Berlin. 



The Magdeburg Water Bridge is a navigable aqueduct in Germany, opened in October 2003. It connects the Elbe-Havel Canal to the Mittellandkanal, crossing over the Elbe River. It is notable for being the longest navigable aqueduct in the world, with a total length of 918 metres (3,012 ft). The Elbe-Havel and Mittelland canals had previously met near Magdeburg but on opposite sides of the Elbe, which was at a significantly lower elevation than the two canals. 


Ships moving between the two had to make a 12-kilometre (7.5 mi) detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, and then sailing downstream on the river, before ascending up to the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo.



In addition to the bridge, a double lock was constructed to allow vessels to descend from the level of the bridge and Mittelland Canal to that of the Elbe-Havel Canal.
Additionally a single lock was constructed at Rothensee to allow vessels to descend from the bridge level to the Elbe and the Magdeburg harbour. This lock is parallel to, and replaces the Rothensee boat lift, and can accommodate larger vessels than the lift.

you can travel on weekdays by bus to the stop "Magdeburg Hebewerk" (ship lift - not in use anymore). From there you can walk across the waterbrigde to Hohenwarthe (2,5 km) or further till the lock Niegripp (bus stop Niegripp Schleuse) (5,5 km). On Sa or Su you can only travel by tram to the end stop Barleber See. From there it's a 3 km walk to the Hebewerk.
