The engineering association Schlüssler-Plan and ILF Consulting Engineers was awarded a contract by the city of Munich for the civil and structural engineering works as part of the modernisation of the Mittlerer Ring road (B2R) – Landshuter Allee (LAT) section, from the northern ramp of Donnersbergerbrücke to the northern Dachauer Straße. Landshuter Allee is one of the busiest roads in Europe (ADT > 100,000 vehicles)
The project comprises the new construction of an approx. 1.5 km long road tunnel. Besides demolishing and modifying the existing engineering structures, it will be necessary to relocate and demolish the existing combined sewers with diameters of more than 3.0 m as well as the connection sewers incl. the necessary sewers in the new section. To maintain traffic throughout the construction period, a temporary traffic routing is needed at Landshuter Allee and a final traffic routing above ground as well as in the new road tunnel.
