Portal Coating for the Tunnel de Choindez on the Swiss autobahn A16

The “Transjurane” is one of the most challenging road projects in Switzerland. With a length of 84 km, the new national autobahn A16 crosses the Jura mountains, running through numerous smaller and larger tunnels. After 30 years of construction time and costs amounting to 6.5 billion Swiss francs, the last section was opened to traffic on 3 April 2017.  The company Silikal Suisse AG was one of the contractors, responsible for the coating of the concrete construction at the portals for the last major tunnel section, the 3.2 km long Tunnel de Choindez, which was opened in December 2016.
