Zurich's northern bypass, one of the busiest road sections in Switzerland, runs through the Gubrist Tunnel. The rehabilitation of the two existing tubes will begin after the construction of the new third tube has been completed. As part of the rehabilitation, the driving space of the existing tunnel tubes is to be enlarged and the roadway lowered by 30 cm.
Implenia's share of the third lot of the renovation contract from the Federal Roads Office (FEDRO) amounts to CHF 74 million. The project will start with preparatory work in the fall of 2022 and last around four years. (aw)
