The story
Via Donau was established on January 1, 2005, by the Ministry for Transport, Innovation, and Technology (BMVIT). It was formed by a merger of the Austrian Donau-Betriebs AG, the Austrian Danube-Technik GmbH, the Via Donau Development Company for Telematics and Navigation on the Danube, and the privatized waterways organization.
