June 2011. CO, NO2, detection and air quality control in tunnel.
The new tunnel at Monrepós has been built with the intention of turning into a dual highway the present road between Nueno and Jaca (N-330). The underground pass, almost 3 Km. long, will provide service to vehicles driving toward the Pyrenees, while the existing two tunnels will take on exclusively with traffic going towards Huesca.
The separation of this prepyrenaic port will become one of the most singular works of the Somport-Sagunto highway due to its technical complexity. The higher stretch of Monrepós-Caldearenas is only 4.1 kilometers long, but includes the 2.9 kilometer tunnel, four viaducts and a smaller tunnel connecting with the present road.
For air quality control and gas detection in this tunnel DURAN ELECTRONICA manufactured and/ or distributed products have been installed, including CO and NO2 detectors, opacimeters and anemometers.
