The ARGE Gubri - composed of Implenia Schweiz AG from Glattpark -Opfikon (40%, leader), Walo Bertschinger AG from Zurich (30%) and Anliker AG from Emmen (30%) – secured the EUR 182.03 (CHF 184.03 million) contract, including 7% VAT, for the renovation of the Gubrist tunnel, tubes 1 and 2 on the N01/38,42 Zurich northern ring road extension: main construction works (Lot 300).
The project starts with preparatory work in autumn 2022 and will last about four years. The existing tunnel tubes are no longer big enough to accommodate today’s traffic, so they are being enlarged: the road surface is being lowered by 30cm and the new suspended ceiling is being made higher. In order to increase safety standards, 22 new emergency bays are being built into the second tube, while the 24 emergency bays in the first tunnel are being renovated.
