Design Competition Mühlenfließbridge

In the Mühlenfließbridge competition, LAP won one of two second prizes; no first prize was awarded.

The Mühlenfließbridge is located in the course of highway A10 of the outer Berlin beltway and is in the immediate vicinity of the Rüdersdorf junction. Extensive damage has been identified in the course of bridge inspections in recent years. After a series of preliminary investigations, it was decided that an economic rehabilitation was not economical and that the bridge should be replaced. Therefore, in May 2020, the Landesbetrieb Straßenbau Brandenburg called for a competition

Since this competition is an interdisciplinary planning task from the areas of traffic facilities, civil engineering including construction logistics, subsoil, noise protection and nature conservation issues, we have formed a team of specialists:

  • Civil Engineering: Leonhardt, Andrä und Partner
  • Traffic Planning: proVIA
  • Environmental Planning: ILF
  • Animation: Morean

Due to the inner-city location of the A10, a particularly large number of complex boundary conditions had to be taken into account, as well as several traffic routes located in the competition area.

Based on a future-oriented use of the area of the Mühlenfließbridge including the Rüdersdorf junction, the focus is on a long-term optimal traffic routing (utilization period 100 years) and simultaneous short-term implementation of the measure.

The two identical superstructures for each directional carriageway are designed as composite plate girders with accessible box girders.

The thirteen-span replacement superstructures will be supported on the existing piers and the laterally supplemented pier plates. For both superstructures, this results in spans of 47.00 - 4 x 61.20 - 2 x 48.70 - 5 x 61.20 - 47.00 m as in the existing structure.

Our design introduces an innovative construction and demolition technology, enables a future-oriented traffic routing and overall guarantees an economical and on-time construction method through early measures. By "bringing forward" individual planning and construction processes, time and financial advantages can be generated.
