Fresh air is blown into the tunnel through the service tunnel and evacuated through the ventilation towers at each end. The Louis Hippolyte Lafontaine Bridge-Tunnel (Pont-Tunnel Louis-Hippolyte-La Fontaine) is a Canadian highway bridge-tunnel running over and beneath the St. Lawrence River. In the old electrical rooms, the existing carbon dioxide systems were restored and carbon dioxide detectors were installed to monitor and alarm any possible gas leakage.To evacuate rainwater from the tunnel there are three pumping stations, one at each end housing 60-HP pumps, and one in the middle housing a 50-HP pump. What we do.

In collaboration with Groupe Sguin-BBA, RSW modernized the pump system with programmable controllers that can collect data in real time.Ventilation in the tunnel is assisted by 16 fans (eight fresh air fans, and eight exhaust fans) ranging from 125 HP to 200 HP. (Roger Nicolet, Armand Couture and Bernard Lamarre were the design engineers. Construction began in 1963 and it opened on March 11, 1967.
