The Tunnelling 20Twenty event will be held in Hong Kong 19-22 September 2011. The conference explores the opportunities in tunnelling and what the international market may look like for the next 20 years. Currently, the Tunnelling 20Twenty website offers a downloadable map with 20 case studies that will be highlighted during the event. These include tunnel projects such as 18km Fehmarnbelt Fixed Link under the Baltic between Germany and Denmark, lessons learned from cave-ins in Beijing, Switzerland’s Gotthard Tunnel, Brazil’s boom, and more.
