Technical specifications

Project description
The MRSW– Luise-Kiesselbach-Platz Tunnel Project is the third section of an infrastructure project at the Middle Ring in Munich ratified by a public referendum in 1996. The project comprises the construction of an approx. 2800 m long inner-city tunnel, in bored pile topdown method and cut and cover construction method as well as canal and road works. All works had to be carried out during ongoing traffic on the surface at all times (approx. 150.000 cars/day) as well as for all utilities in operation and thus required many traffic diversions and numerous construction sections. The heart of the tunnel is considered to be the 2-storey construction of the intersection between motorway connection A95 and Middle Ring to the East and North.
