September 2011. CO, NO2 and Air control in tunnel.
The double tunnel at Montgros is part of the C-15 stretch between Vilanova y la Geltrú and Vilafranca del Penedès. It is a 13 kilometer stretch with dual carriageway characteristics with two lanes in each direction. The tunnel – which has already been built – has two tubes, one for each direction. The first has a length of 1,593 meters and is 12 meters wide, and the second, parallel to this, is a little longer – 1,606 meters -.
These two new passes will be integrated in the new C-15 road from its link with the C-32 highway, near the locality of Sant Pere de Ribes, up to the northern link of Canyelles with the C-15b. The tunnels are connected with each other by three galleries to ease evacuation in case of an emergency. Once drilling work has been finished, lighting, ventilation and environmental control have been installed, as well as signs and security & control systems.
For air quality control and CO and NO2 detection, equipment manufactured and/or distributed by DURAN ELECTRONICA has been installed in the tunnel, such as opacimeters and anemometers.
