The port was expanded in the 1920s and 1930s by adding new docks as well as on the administrative infrastructure (Dortmunder Hafenamt).
Gaining its greatest importance after WW II, in 1972 6.2 million tonnes of good were shipped over the port.
2.96 million tons of freight were shipped over the Dortmund Port in 2007, an increase of 7.1 percent compared to the previous year.
[1] In the process of restructuring the industry in the Ruhrgebiet and in Dortmund, local politicians are looking for new ways to use the old port.
Planned projects are the construction of a marina and high-quality areas for recreational use and residential redevelopment on the water.
