N01 Lenzburg South junction optimisation, pedological building management (PBM)

The project

Place: Lenzburg (AG)
Customer: Federal Roads Office ASTRA
Phases: Detailed project planning, submission (until 2019), implementation and commissioning from 2020
Period: 2017-2010
Construction costs: Approx. CHF 10,000,000

 

Due to increasing traffic counts as well as the existence of an accident black spot according to the VSS standards, ASTRA planned a new motorway input that is almost completely located in forest area. The project is therefore associated with a large loss of forest soil. However, dismantling the existing feeder allows for the creation of additional soil area in the agricultural zone. The pedological building management (PBM) was contracted as part of the environmental building management (EBM).
