C-Matrix organised and held the launch ceremony for the Swiss Federal Roads Office (FEDRO) to celebrate construction starting on the third tube of the Gubrist tunnel located on the A1 motorway’s northern Zurich bypass.
On 21 November 2017, the first blast for the third tube of the Gubrist tunnel was carried out in Zurich-Affoltern. With this ceremony, the Swiss Federal Roads Office reached another milestone. Blasting is being used to construct the third tube of the Gubrist tunnel and 6,000 explosions will be needed over the course of the next two years. Alongside advocate for the tunnel Maya Grossmann, Max Walter and Hanspeter Haug, the mayors of Regensdorf and Weiningen, pressed the red button to trigger the first blast for the third tube of the Gubrist tunnel. The breakthrough for the three-lane tunnel, which will be three kilometres long and have a diameter of almost 16 metres, is planned for 2019. Commissioning is scheduled for summer 2022.
