With Hamburg Elbbrücken several independent bridge structures are designated, which cross the river Elbe in Hamburg. Within Hamburg, this navigable waterway is divided into two main arms, the Norderelbe and the Süderelbe, which, after sealing off the Alte Süderelbe, reunite with the Norderelbe via the Köhlbrand, bypassing the Elbe islands, which are the largest river island on the Elbe.

Really worth seeing building over the Elbe. It's worth staying briefly on the bridge with a great view of the port of Hamburg, other bridges and of course the Elbe.
