Numerous electronic and mechanical elements have to be installed in order to ensure the safe operation of the tunnel: lighting, ventilation, communication technology (for users, operations, the police and emergency organisations), video surveillance, fixed and variable signage, escape route installations and fire equipment. Traffic, temperature, fire and fault sensors monitor the situation in the tunnel on an ongoing basis. The installation of these elements will take about two years. 

The ventilation system is the tunnel's most energy-intensive system and accounts for around 85% of the total energy requirement. During operation, it is estimated that the ventilation of the tunnel system will require some 10 GWh of electricity every year, equating to the power needs of around 2000 households.
