Transport ministers Philippe Tabarot and Matteo Salvini inaugurated the new Fréjus tunnel, which now separates the directions of traffic between France and Italy in two separate tubes. This is the culmination of a long-term project started in 2009 by the i3S consortium comprising SYSTRA (lead), SWS (civil engineering) and Geodata (geology – geotechnics).
For 10 years, SYSTRA was in charge of the engineering and construction of this tunnel, carrying out the studies and approvals, managing the construction contracts and monitoring the work on site, right up to the handover of the project on 31 January 2020.
The entire project was carried out without interrupting traffic in the historic tunnel, which has been in service since 1980 and runs parallel to the new route. This project has enabled SYSTRA to strengthen its expertise in the management of underground projects and to work closely with the SWS teams, which were integrated into SYSTRA Italy in 2021 .
Today, the Fréjus tunnel is the longest double-tube road tunnel in Europe. Every year, almost 2 million vehicles, including 1 million heavy goods vehicles, use this vital link between Modane in France and Bardonecchia in Italy. Following a road accident in 2005, it was decided to double the infrastructure by digging a second tunnel, initially designed as a safety gallery, which in 2012 became a fully-fledged road tunnel to separate the directions of traffic.
