A huge improvement
crossing The left picture clarifies the enormous improvement, achieved by building the red-coloured locks and the canal-bridge. Before the Wende (https://en.wikipedia.org/wiki/Peaceful_Revolution) ships travelling from west to east had to descend the Schiffshebewerk Rothensee, cruise downstream on the river Elbe, again descend the Schleuse Niegripp (hence the enormous height difference with the, new, Schleuse Hohenwarte) and end up in the Elbe-Havel Canal.

And the other way around, of course, when travelling east-west. The building of the red coloured state-of-the-art works ended in 2003. The right picture gives a good impression of the entire area. Number 1 is the Schleuse Rothensee (https://de.wikipedia.org/wiki/Schleuse_Rothensee), 2 the Schiffshebewerk Rothensee, 3 the Kanalbrücke Magdeburg, 4 the Schleuse Hohenwarthe and 5 the Schleuse Niegripp. We were moored in the short arm, leading to 2, the Schiffshebewerk Rothensee.
