We regularly report on the construction of the Kalocsa-Paks Danube Bridge. The structure reached its highest point at the end of April 2023. In the Építési és Közlekedési Minisztérium (ÉKM) investment, in the project implemented by Duna Aszfalt Zrt. project, Hídépítő Zrt. is also participating as a subcontractor in the project.

At the end of July, István Wunderlich, project manager of the Duna Aszfalt again informed us about the current state of the works.

"The lengthening of the bridge structure on the right bank has been completed, and a 2,000-tonne steel superstructure 286 metres long has been put in place. The push-pads have been removed from underneath the bridge and the installation of the final supports for the bridge, the hinge structures, is underway.

The assembly area of the right floodplain bridge has been dismantled, so that the construction of the reinforced concrete frame structure on the saved side of the flood protection embankment can begin, which will ensure the smooth traffic flow for the water management authorities and the emergency services under the newly built road No. 512."

International shipping traffic will continue to operate without disruption during the construction

As the expert put it, "the fans on the viaduct are becoming more and more spectacular."

At the time of taking the photo gallery, the 5th pier above the Danube, which is 40 m above the average water level, already had 4 levels (4×4=16pcs) of cables supporting the load of the free-mounted bridge, while the 6th pier above the Danube had 3 levels (3×4=12pcs) of cables stretched by the PANNON-FREYSSINET Kft. specialists.

In this phase, the main span of the Kalocsa branch of the bridge will extend 62.5 to 62.5 to 62.5 metres from the abutment, while the Paks branch will extend exactly 1 metre, 57.5 to 57.5 metres, above the international shipping route, which will remain in uninterrupted operation throughout the project.

On the left river bridge structure, the installation of the bridge accessories (raised parapet, bridge parapet, railing and candelabra girder plates) has been completed in phases, followed by the corrosion protection and waterproofing works.

"The stone dikes diverting the Danube water into the new bed have also been completed on both the upstream and downstream sides of the new Danube bridge", the expert concluded (the dikes will divert the main river in the direction favourable to the bridge, reducing the load on the new bridge piers - ed.).
