Magdeburg Magdeburg Water BridgeWater BridgeBy Brynn English

Background Background InformationInformation--The Magdeburg Bridge spans the Elbe River and connects the Elbe-Havel Canal to the Mittelland Canal.

--Only open to river barges with loads to transport.

--Engineers first dreamt of joining the two waterways as far back as 1919. Construction started in the 1930s, but was halted by WWII and started up again in 1997.

--Six years, 24,000 metric tons, and 68,000 cubic meters later, the bridge was completed (October of 2003).

Background Background Information Information (cont.)(cont.)--The Elbe-Havel and Mittelland canals had previously met near Magdeburg but on opposite sides of the Elbe.

--Ships moving between the two had to take a 7.5 mi detour descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sail downstream on the river, before entering the Elbe-Havel Canal through Niegripp lock.

--The Bridge is not tolled, and never will be.

Interesting Interesting FactsFacts

--The bridge only needed to be designed to withstand the weight of the water. The amount of water that is displaced weighs the same as the ship, so it does not depend on how heavily it is loaded.

--Shipping can often come to a halt on the stretch if the river’s water mark falls to unacceptably low levels.

Interesting Interesting Facts (cont.)Facts (cont.)

--Ships can carry loads of up to 1,350 metric tons – the equivalent of 50 truckloads – over the bridge. Previously, ships could only be loaded with 800 metric tons.

--Low water levels in the Elbe often prevented fully-laden canal barges from making this crossing, requiring the time-consuming off-loading of cargo.
