Munich: Extension of Northern Urban Beltway - Section Petuelring / Schenkedorstrasse


In the Munich area the Urban Beltway is the road with the highest traffic load amounting to a maximum volume of approx. 130,000 vehicles a day.
In 1965 Dorsch Consult was authorised for the first time to design the Urban Beltway. Up to present the company has participated significantly in the conceptional design and extension of this high-capacity beltway, which is part of the Munich urban history of construction.
Due to a great number of problems to be solved (buildings, canals, underground and metropolitan railway traffic having to continue uninterruptedly during construction period) planning was based on a high degree of difficulty.
The Petuel Tunnel Project – one of the most modern tunnel structures and the road extension of the urban beltway – was a new challenge for us again and again.
