Socialist Federal Republic of Yugoslavia
Regarding rivers, the Danube was navigable throughout its entire course in Yugoslavia, linking the ports of Belgrade, Novi Sad, and Vukovar with Central Europe and the Black sea. Long stretches of rivers Sava, Drava and Tisza were also navigable.
Ferenc Reitter
Reitter planned the route to follow a major swampy branch of the Danube river, which swings eastward in a large arch from Danube to Danube over a distance of 4.141 meters. The canal passed through a suburban district of narrow streets and, at the time, Reitter also considered making the backwater into a navigable canal to improve the air quality and lessen pollution.
