Austria Invests €73.5 Million in the First Phase of Danube Bridge Modernization

The government of the Austrian federal state of Lower Austria has approved the awarding of contracts for the construction of a temporary bridge and the renovation of the piers of the historic Stein–Mautern Bridge across the Danube.

The project organizers announced the decision on 3 November 2026.

The investment in the first phase of the reconstruction project will amount to approximately €73.5 million.

Construction of the temporary bridge is scheduled to begin in mid-2027. It will be located approximately 25 metres upstream from the existing bridge, with the main structure spanning about 335 metres across the Danube.

Following an estimated 14-month construction period, traffic will be diverted to the temporary crossing, allowing comprehensive reconstruction of the historic bridge to commence.

The project includes preserving the bridge's distinctive steel structures, widening the carriageway, and developing modern pedestrian and cycling infrastructure.

Completion of the reconstruction and reopening of the historic bridge to traffic are scheduled for 2032.

Commentary by the Institute of Danube Research

Austria's approach demonstrates the importance of comprehensive planning in the modernization of transport crossings over the Danube.

A key feature of the project is the integration of historical engineering heritage preservation with improved transport functionality and safety.

For the Lower Danube countries, this experience may provide valuable lessons in preparing new bridge projects, particularly those connecting Ukraine and Romania.

According to the Institute of Danube Research (IDR), the development of cross-border transport infrastructure should be based on long-term freight traffic forecasts, environmental impact assessments, and integration into the Trans-European Transport Network (TEN-T).
