The escape route for pedestrians via the planned new evacuation tunnel will be 1,100 metres – including eleven shelters for people blocked in case of disaster. That is by itself a gigantic project. And it is the Principality who is the operator of the Rainier III tunnel which in total covers 1,560 metres. Approximately 350 metres are in Monaco and the rest is in France. Monaco’s share of the cost to fund the drilling and development of the pedestrian gallery on the rock is around 60 million euros.
Do you remember that twenty years ago, a refrigerated lorry burst into flames in the middle of the Mont-Blanc tunnel.
