The Sava River is classified as a international waterway class IV from the border of the Republic of Serbia (rkm 211) to Sisak (rkm 594). Currently, the Sava river waterway does not meet the required navigation parameters of international waterway class IV and does not allow for smooth navigation on 300 days/year for vessels with a maximum draft of 2.5 metres.This project will result in the improvement of the physical capacity of the waterway of the Sava river and it will contribute to the improvement of mobility and multimodality in the Danube Region. At the same time, it will contribute to the increase of river transport, to the removal of obstacles to navigability and to the establishment of effective waterway infrastructure management in the Danube region.The main objective of the project is the integration and modernization of the Croatian infrastructure within the Trans-European Transport Network. As an international waterway, the Sava river does not meet the navigability criteria for the European inland waterways as provided in the AGN Agreement, since it should enable safe navigation for vessels of class IV for 300 days per year.
