The tunnel is characterized by valuable details (materials and finishing) aimed at improving the quality standard and technological level of the work; the design considers the problems related to the location of services, the equipment of lighting systems, traffic control and environmental safety. It also boasts high-level technological performances in terms of safety, air quality, sound insulation and systems and installations.
A number of technological systems have been implemented for detection of air quality, vehicle counting, vehicle speed, fixed and variable-message traffic signs, timed and interconnected traffic lights and for signal repetition for mobile phones.
Ventilation under the tunnel is natural in ordinary conditions; when the predefined pollution thresholds are exceeded, a powerful mechanical ventilation system is activated, consisting of axial accelerators (longitudinal forced aeration).
The tunnel lining is made of highly sound-absorbing panels consisting of elements of aluminum perforated sheet.
