Construction of replacement bridges for the two harbour bridges spanning the Main-Danube Canal and the South-West Bypass / A 73:
- 20,000 m³ of excavated soil
- 12,000 m³ of backfill
- approx. 4,000 m of bored piles (Ø 1.2 m)
- 7,500 m³ of reinforced concrete
- 2,100 tonnes of reinforcing steel
- 4,900 tonnes of structural steel
- Joint venture with SEH Engineering GmbH and Mostostal Krakow S.A.
The bridge structure spanning the Main-Danube Canal consists of an overhead, single-piece steel superstructure with a spatial truss structure and box-shaped stiffening girders. This construction method allows the bridge superstructure to be prefabricated away from the traffic routes. It is then swung into place or floated into position whilst prefabricated. This significantly reduces the time periods during which traffic and shipping operations are disrupted.
The bridge over the South-West Bypass is also being constructed with a height offset to ensure traffic flows as smoothly as possible.
Upon completion, both bridges will each have two lanes in both directions (into and out of the city), as well as a combined footpath and cycle path.
