24 hours a day, seven days a week, ATMB teams are on duty to ensure the highest level of driver safety in the Mont Blanc Tunnel, as well as on the A40 motorway and the Route Blanche (route RN205). Innovation is central to ATMB’s safety policy and we use all the latest safety technology.
Road safety specialists at your service
Mont Blanc Tunnel
Traffic safety operators man the ATMB Command & Control Centre 24/7. This “control tower” has a threefold mission: to oversee traffic, manage safety equipment, and inform drivers of traffic conditions.
ATMB Safety teams serve and protect users in case of an incident. They are equipped with special vehicles to act immediately in the field. In emergencies, they work with fire-fighters.
Safety and traffic assistants regulate and control lorry traffic.
70 fire-fighters work 24/7 at stations located at both entrances and in the middle of the Tunnel. They are specialized in working in confined conditions. Rapid intervention being key to safety, they respond fast.
In case of a major emergency, French fire-fighters from Chamonix and Italian fire-fighters from Courmayeur work together. Thanks to regular drills, they know the tunnel perfectly. Their imperative: to coordinate the fire brigades effectively to resolve the emergency quickly.
Over 250 people dedicated to Mont Blanc Tunnel safety.
Training and drills
Every morning, Tunnel fire-fighters go through drills designed to test their reflexes and speed. In addition, GEIE-TMB (the Mont Blanc Tunnel European economic interest grouping) holds four major exercises a year with the French and Italian authorities, based on an emergency scenario kept top secret until the last moment. Nearly 200 people are mobilized to test the effectiveness of emergency procedures and systems.
Safety teams also train regularly on a 3D simulator. In all, Mont Blanc Tunnel staff get over 3,500 hours of training per year.
200 people take part in each major emergency drill.
Autoroute Blanche (A40 motorway) and Route Blanche (Route RN205)
Over 70 people work around the clock on surveillance, safety, traffic control and maintenance of the A40 motorway, also known as the Autoroute Blanche. Beside them, over 50 people ensure safety and service 24/7 on Route RN205, aka the Route Blanche. Their missions: to supervise traffic via security cameras, inform and assist drivers in the event of an incident, patrol, maintain roads and remove snow…
In addition, 84 specialists in civil and mechanical engineering technologies look after infrastructure and safety equipment.

Cutting-edge equipment in the Mont Blanc Tunnel
Major investments for the Tunnel
Nearly 400 mn. euros were invested in the Tunnel re-opening after the fire in 2002.
Each year, major investments are made by ATMB and our Italian counterpart, SITMB, to ensure safety. In 2016, ATMB and SITMB each invested €5.5 mn in the Mont Blanc Tunnel - a total of €11 mn dedicated to innovation and safety in the Tunnel.
€5.5 mn invested in 2016.
New centralised technical management tool
The Mont Blanc Tunnel has a brand new centralized technical management tool (CTM). This is a computerized safety equipment control system which includes the latest data processing technologies and training simulation applications. It continuously analyzes over 100,000 items of data from various devices throughout the Tunnel, such as cameras, thermometers and opacimeters (smoke and emission meters).
When an incident occurs, operators use the CTM to take immediate action, according to pre-established procedures (e.g. display warnings on electronic road signs, switch on ventilation, lower barriers to interrupt Tunnel traffic).
Total 2016 investment: €1,300,000 (ATMB’s share: €650,000).
€650,000 € invested in 2016.
Proteus: cutting-edge fire-fighting vehicles
Tunnel fire-fighters are equipped with four Proteus lorries, the only fire-fighting vehicles of their kind in the world. The Proteus has a 12,000-litre tank, and two fire hoses with a 60-metre range, as well as latest-generation thermal cameras and radar to advance regardless of visibility. Each vehicle represents an €800,000 investment.
On the A40 motorway and the RN205
The Sierra control room: the nerve centre of the A41 and Route Blanche safety system
The new control centre, named Sierra II, centralizes and controls all Autoroute Blanche (motorway A40) and Route Blanche (route RN205) equipment in real time. Sierra operators monitor traffic and network conditions with dedicated equipment (e.g. video cameras, counting loops, weather stations, incident detectors), take emergency calls, trigger emergency procedures, and inform drivers.
SIERRA II is connected via a high-speed fibre-optic network to over 7,000 checkpoints throughout the network. A video wall made up of sixteen screens and a 2x2m flowchart keeps operators informed in real time, 24/7, and allows them to act immediately if necessary.
7000 points continuously checked by control centre operators
Investments for Route Blanche (RN205)
Since 2010, ATMB has been implementing a major investment programme for the Route Blanche (route RN205). €40 mn have been invested to enhance traffic safety and flow on this 20-km link between the Autoroute Blanche (Motorway A40) and Chamonix and the Mont Blanc Tunnel.
The Route Blanche (route RN205) culminates at an altitude of 1,274 m, and includes 53 bridges (including the impressive Egratz viaduct (1,470 m long and 68 m high) and three tunnels (including the Chavants tunnel (1,015 m long).
ATMB’s objective is to provide the same levels of service and safety for this road as those for the A40 motorway (Autoroute Blanche).

The Egratz “hard hat”: an amazing feat of engineering for safety
To protect against falling rocks on the downhill stretch of the Egratz Viaducts on the Route Blanche (route RN205), ATMB has achieved an awesome feat of engineering: a 110-meter-long rock shed, nicknamed the “hard hat”, overhanging both lanes of traffic. The structure is held up by the rock wall via sixty-five 80-tonne support bars. The system includes 20,000 m² of protective screening. Three years were required to complete this amazing construction job.
The next step is to renovate all three Egratz viaducts, the longest of which (1,500 m) culminates at a height of 68 m. Works started in the Autumn of 2015 (mainly on restraint systems) and are expected to end in 2017.
