Construction work has started in Sisslerfeld

In January 2026, construction work on the ESP Sisslerfeld – Südspange Eiken/Münchwilen area development project got off to a successful start. This project will further improve access to the Sisslerfeld area and expand the existing road and path network.
The overall project is divided into three lots. As a partner in the engineering consortium, we are responsible for construction management in all lots. Lot 1 involves the construction of a new railway underpass for private tracks, including the associated retaining walls. The planning for this section is being carried out by our team in Olten.
Work is currently underway on the new road drainage system, which is expected to be completed by April 2026. Construction of the underpass is scheduled to start in mid-April.
