It only needs to be designed to withstand the weight of the water!

( t& D! M1 r" W! q' D' c7 MThe Incredible Magdeburg Water Bridge in Germany
' U: E+ j: j5 d6 S8 G: T& oThe Magdeburg Water Bridge is a navigable aqueduct in Germany that connects the Elbe-Havel Canal to the Mittelland Canal and allows ships to cross over the Elbe River. At 918 meters, it is the longest navigable aqueduct in the world. P: I' H- ]4 L: g9 e* |7 o' R# r, F
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 make a 12-kilometer detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before entering 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.

Construction of the water link was started as early as in the 1930s but due to the World War 2 and subsequent division of Germany the work remained suspended till 1997. The aqueduct was finally completed and opened to the public in 2003.
