Transnational project (DE, RS) Restoring unhindered navigation on Serbian inland waterways by cleaning of UXO left behind after the NATO bombings in 1999 in the Danube and Sava rivers. According to the IWT Master Plan of 2008, there were 8 critical locations on the Danube and 4 on the Sava river.

Transnational project (ES, IT, RS) The old Zezelj bridge was destroyed in NATO air strikes in 1999. The temporary constructed bridge did not comply with the required standards of the Danube Commission and EU standards. The new Zezelj bridge (within the European Rhine-Danube Corridor) was reconstructed until 2018 at the same location using the foundation of the bombed bridge.

National project (DE) The Danube river section from Straubing to Vilshofen is a major bottleneck in the Trans-European Network. The task of this already concluded study was to examine the two remaining variants and to prepare technical and ecological planning for both variants. The aim was to bring about the final decision concerning the development of the Danube between Straubing and Vilshofen.

National project (DE) The Danube river section from Straubing to Vilshofen is a major bottleneck in the Trans-European Network. After conducting a variant study in 2013, policy-makers decided to pursue variant A. This follow-up study laid out the necessary preconditions to obtain the construction permissions and budget approvals for the upgrading of subsection 1 Straubing-Deggendorf.

National project (HR) The Sava river is navigable on 594 km of its river course and links the economies of the four Sava riparian states (Serbia, Bosnia and Herzegovina, Croatia, Slovenia). This project will result in the improvement of the physical capacity of the Sava waterway and it will contribute to the improvement of mobility and multimodality in the Danube and Sava region.

Transnational project (NL, DK, RS) Critical sections on the Danube River in Serbia are identified in the Master Plan for IWW Transport in Serbia (2006). River training works are needed in order to achieve fairway parameters which would improve navigation conditions in terms of safety. Necessary designs and tender documentation for river training works on six critical sections on the Danube River in Serbia were elaborated.

National project (RO) The project foresees further bank protection works on the Sulina Channel (on a length of 36.7 km), in addition to the works already concluded (lenght of 15km).

National project (RO) As a consequence of critical points on the Călăraşi – Brăila section of the Danube, vessels must take a bypass route via the Bala–Borcea branch, which extends the navigation distance to around 110 km, for periods of around 140 – 160 days/ year. The project therefore includes river engineering works which will ensure navigation levels on the Old Danube and have a reduced impact on the environment, having effects only during low water seasons.
