Need  and  added  value  for  the  Danube  Region  Strategy

The Main is 524 km long, of which 388 km are navigable. The Main connects the Rhine and the Danube via the Main-Danube Canal and is therefore an important part of the inland waterway network of the Danube Region. Currently, the possible draught in the Main stretch between the Rhine mouth and Aschaffenburg is 2.9 m. All measures concerning the upgrade of the waterway infrastructure at the Main are thus beneficial for waterway transport in the entire Danube Region.


Sole objective of this infrastructure project is the deepening of the fairway on the Lower Main between the Rhine mouth (rkm 0.0) and Aschaffenburg (rkm 84.5), in order to enable a draught of 3.1 m.
