This paper presents a case study entailing the reconstruction of a road bridge. The original timber construction low-level bridge with rolled steel girders had lost its performance parameters due to biological corrosion of the structural timbers. The support piles were defective. The structure was taken out of use and a solution was proposed in the form of a composite span structure founded on prefabricated reinforced concrete piles. It is important to pay attention to the economic considerations of the reconstruction, as managers of lower category roads often only have a rather limited budget.
