Motorway bridge over the Drava

Datos de Proyecto

Ubicación: Osijek, Croacia

  • New construction of a 2,485 m long bridge as part of the A5 motorway development in eastern Croatia, consisting of one suspension bridge and approach bridges in the flood area of the River Drava.
  • Two foreland bridges each approx. 1,000 m long, designed as beam bridges each with 35 m span widths
  • construction with pre-fabricated pre-stressed concrete beams
  • supported on circular reinforced concrete piers with 180 cm diameters and mushroom-shaped heads.
  • Cable-stay bridge with 3 segments (100 m / 220 m / 100m spans), suspended on two A-shaped pylons with heights of 75 m
  • carriageway realized using a steel composite construction.


  • circular columns (180 cm diameters) with mushroom-shaped heads
  • formwork for the field factory for construction of pre-stressed, I-shaped bridge beams
  • reinforced concrete cantilevered parapets for the edge and middle areas of the two separated carriageways
  • climbing formwork for the pylons with a constantly changing cross-section
  • short construction time, fastest-possible adaption of the formwork solution to the existing cross-sections
