RhineDanube

RhineDanube refers to the integrated river transport system that links the Rhine and Danube basins in Central Europe. The most significant component is the Rhine–Main–Danube Canal, completed in 1992, which connects the Rhine near Mainz with the Danube near Kelheim by crossing Bavaria and Austria via the Main and Danube rivers. Together with the natural waterways, this link creates a continuous navigable route from the North Sea to the Black Sea for inland ships.

Route and operation: The Main River provides the connection from Bamberg toward the Rhine, while the canal segment between Bamberg and Kelheim includes a series of locks and basins that enable vessels to move between the two river systems. The Rhine–Main–Danube linkage forms a major trans-European transport corridor, enabling year-round inland navigation across a large portion of Central Europe.

Economic and strategic significance: RhineDanube is a core element of the Trans-European Transport Network (TEN-T). It supports freight transport, logistics, and regional economic development by providing an inland route that helps to reduce road and rail congestion and associated emissions. The corridor also underpins cross-border trade and access to inland markets for multiple countries along its course.

Operations and governance: Maintenance and modernization are carried out by national authorities in coordination with the European Union and neighboring states. Projects typically focus on enhancing lock capacity and safety, dredging, and corridor integration to improve reliability and efficiency for inland shipping.
