The Gubrist Tunnel is a motorway tunnel in Switzerland. It lies to the north-west of the city of Zürich, and forms part of the A1 motorway, on its northern ring section around Zürich. The tunnel was completed in 1985, and is in length.
The tunnel is named after the hill of Gubrist, which is nearby. In 1990, 63,000 cars used this tunnel daily; in 2014, that number had risen to 106,000, and in 2023, the tunnel conveyed 120,000 cars per day.
The tunnel forms part of the 'A1 Nordumfahrung' renovation plan covering the western entrance, the Gubrist Tunnel itself, and a further of motorway west of the tunnel. The project will expand the motorway approaching the tunnel from its original four lanes (two in each direction) to six lanes (three in each direction). The major junctions immediately east (the Weiningen junction) and west (the Affoltern junction) of the tunnel will also be modernised. The project will cost in total 1.55 billion Swiss francs. Work started in 2014 and was scheduled to take nine years; in July 2023, the third tube was inaugurated.
