A1 expansion northern Zurich bypass

On Saturday, April 15, 2023, more than 20,000 visitors took the opportunity to participate in the «tunnel festival» and inspected the new third tube of the Gubrist motorway tunnel  Bicycles were available for transiting the whole length of the tunnel and were in constant use from 10 a.m. to 10 p.m. in both directions. Many guests also enjoyed the tunnel atmosphere by taking a ride on the rubber-wheeled sightseeing train. In addition, the program included a show presented by the emergency services, tours of the huge control centers and a wide range of catering options.

Early on Thursday morning, April 20, 2023, the third tube of the Gubrist tunnel was commissioned. Westbound traffic has been flowing through the new tunnel tube since shortly before 4 a.m. As part of the drainage, surfacing and foundation work has not yet been completed, some construction space is still required in Weiningen. Therefore, for the time being, only two lanes are available for traffic in the new tube. The official opening with the release of the third lane will take place on July 3, 2023 in the presence of Federal Councillor A. Rösti.

The commissioning of the third tube of the Gubrist tunnel has been postponed until spring 2023 due to the current global economic situation (Covid).

During the night of April 22/23, 2023, there will be a "silent opening" of the third tube to regular traffic. A public festival and the authorities’ event are expected to take place in mid-April 2023.

In early May 2023, the renovation work of the existing second Gubrist tube will start. Westbound traffic (direction Bern) will be accomodated on two lanes in the new third tube, while eastbound traffic (direction St. Gallen) will occupy two lanes in the first tube.
