The works are in full swing after a successful start. The first step will be to broaden the route and to take the first measures for the covered gallery of Katzensee. The ramps at the junction Zürich-Affoltern will be rebuilt as well. The first construction phase is expected to be completed in 2017. The works on the Stelzen Tunnel, which include the maintenance work on the covered gallery as well as the construction of two new operation centers, have also successfully begun.
