IMPROVED VENTILATION AND LIGHTING IN THE MONT BLANC TUNNEL

Following thirteen years of operation of the Mont Blanc tunnel the rapid growth of traffic has given rise to problems of traffic control and safety. A programme of improvement described in the article concerns lighting and ventilation, the layout of the Italian service area, and, the mechanisation of the toll collection system. Low pressure sodium vapour lamps were chosen to increase and improve tunnel illumination. To increase tunnel ventilation a semi semi-transverse system will deliver 600 cu m/sec and extract 300 cu m/sec. The remaining 300 cu m/sec will pass freely out of the tunnel entrances. Ducts distribute pure air and extract polluted air. Details are given of ventilation equipment performance and of measures taken to control air pollution. /TRRL/
