The new bypass will connect the lower Aare valley with the A1 and A3 motorways and provide access to Brugg/Windisch.
The Brugg south-west bypass project consists of three sub-projects, the new construction of the south branch of the K128, the new construction of the west branch of the K128 and the new construction of the connecting link K401. This new bypass will connect the lower Aare valley with the A1 and A3 motorways and provide access to Brugg/Windisch. Within this project, a complete two-lane road construction with two concrete roundabouts including various works and drainage lines was realised. Various concrete retaining walls with noise protection elements, bridge renovations and new bridge constructions, renewal and renovation of level crossings and compensation measures round off the complex overall structure.

The biggest challenge was to shorten the construction time by one year during the course of the project, which was an enormous coordination effort and feat of strength. Thanks to project optimisations, bundling and cooperation of various departments and specialities from the Civil sector, we were able to present our professional competence and clout impressively and successfully.
Thanks to Circular Economy, we were also able to demonstrate how construction and resource conservation can be brought into harmony.
