The project

Place: Baden (AG)
Customer: Federal Roads Office ASTRA
Phases: Implementation and commissioning
Period: 2018
Construction costs: Approx. CHF 10,000,000


The Baden-West motorway connection was built in 1969/1970 and has not been subject to major refurbishment since that time. Extensive maintenance measures were implemented for the repair of the existing infrastructure (including various engineering structures). Two areas in the agricultural zone were developed as installation places for construction site equipment. The affected soils had to be protected using suitable means and appropriately recultivated after conclusion of the construction work.
