— Project Description:

“La Maddalena” exploratory adit was originally planned to be 10km-long and excavated by an open TBM (diam. of 6.30m) from a portal located near the village of Venaus in the Susa Valley. In 2005 the project came to a stop due to repeated protests of inhabitants and a new alignment was studied for the rail line, including the base tunnel and the exploratory adit, relocating the portal at a site known as “La Maddalena” near the village of Chiomonte, shortening the adit length to 7.5km. The new solution was approved by the Italian government in 2010. Works have been underway since 2011. Once in operation the adit will be used for ventilation, maintenance and safety purposes or as emergency access to the 53km-long Base Tunnel.
