Viaduct Dobovo

The motorway crosses the valley of Dobovo stream with two parallel 255m long semi-integral structures in demanding alignment conditions. The viaducts are continuous over nine spans with a superstructure of prestressed RC slab with long cantilevers.

Due to extremely unfavourable carriageways elements, the continuous prestressed RC superstructures were built in situ on fixed scaffolding. Superstructures were built incrementally span by span in ten day intervals with optimal use of unified steel false-works.
