We have published many reports about the ongoing renovation works of Hungary’s iconic Chain Bridge. The project started in June 2021 because experts said in 2019 that the bridge was no longer safe. The leadership of Budapest plans to inaugurate the renewed bridge in 2023 at the latest. That is because they would like to celebrate the 150th anniversary of Budapest’s birth with the new Chain Bridge.
As we reported before, the Hungarian A-Híd Ltd. is renovating the patinated capital bridge. The company with the largest Hungarian bridge-building history won the public tender for the project for a net amount of EUR 52.9 million (~HUF 18.8 billion). Within the framework of the renovation, the following works will be carried out:
They will also take care of the riverbed arrangement while working with the highest quality and greatest care on the 172-year-old monument. This phase will include the Danube riverbed and the modernisation of navigational signals (construction of active radar), the reconstruction of pedestrian underpasses and stairs, and the renovation and utilisation of bridgeheads.
According to Magyar Építők, the contractors showed the progress they made and shared details about the current phases. They also included how the extreme cold weather affects their work. In December, work was finished by putting the last steel track plate into place.
Magyar Építők said that the workers use technologies adequate for the weather. Furthermore, they try to progress with project elements that can be completed under the surface, inside the bastions or in the chain tunnel. For example, they provide heated tents for their workers to weld. As a result,
they can work without any interruption.
The contractors are adapting the working conditions and working environment to the winter, the strong wind, the freezing temperatures, and the early dusk.
In the heated tents, they continuously provide the necessary temperature. As a result, they can pre-heat the materials they use. Beneath the bridge, they also created heated areas to continue correcting the defects of the bridge structure. Those working outdoors are provided more time to spend in heated areas and can receive hot drinks. Of course, A-Híd calculated with the cold weather. Thus,
they planned the elements of the project to be carried out during winter.
On the Pest side, they are working in the chain tunnel and chamber. There, they are completing the corrosion protection of the structure. They started injecting in the chain chamber and tunnel on the Buda side. This means that the coating will defend the material from getting wet.
already put the first elements of the new sidewalk in their place.
They will build 100 of them between the two pillars of the bridge. Most of these units are ready, and many are already on site. Furthermore, they built a new inspection walkway under the bridge. That will be crucial for the bridge master, who will do the prescribed analysis by walking on it.
