During the renovation and reinforcement of bridges and structures, the extent of intervention can vary significantly. Fundamental renovation operations include the replacement of pavements, repairing damages, replacing corrosion protection coatings, and subordinate elements. Another category involves the replacement of structural elements. For example, during the renovation of the Elizabeth Bridge in Komárom, in addition to pavements and coatings, the upper cross-ties of the arches had to be replaced, and certain elements of the main girders and deck structure were reinforced to increase the bridge’s load-bearing capacity to 40 tons.
For capacity expansion (e.g., creating a bicycle path), increased traffic loads, or insufficient load-bearing capacity of the bridge, it may be necessary not only to reinforce the structure but also to reduce undesirable stresses by installing tensioning elements. We had the opportunity to plan such reinforcements, including at the Rábahídvég Arch Bridge, the Százlábú Bridge in Szolnok, and the bridges at Szövő Street and Tetőfedő Street on the M7 motorway. The special feature of the reinforcement of the Százlábú Bridge in Szolnok is that the eccentricity of the longitudinal tension resulted in transverse tension as well.
In some cases, complete replacement of the structure is necessary: in the case of the Nadányi Zoltán Bridge at Bakonszeg, a new composite structure was built in place of the old bridge.
