Gotthard (2007-2010)
The Gotthard Base Tunnel in Switzerland is at the heart of the new transalpine rail route. With a length of 57 km, the world's longest tunnel has become operational at the end of 2016. In February 2010, the average daily advance rate of the tunnel boring machines was 17.6 meters. The whole project will result in two base tunnels under the Gotthard and the Ceneri. Planning and construction of the tunnels extends over a period of approximately 25 years. The images of the series "Gotthard" were done during many visits in the tunnel from 2007 until 2010 with a 6x17 cm panorama camera.
