Background on Hai Van Pass Tunnel

The tunnel project encompasses a two-lane highway of 12,182 meters in total length. It includes a 6,274-meter long tunnel section, bridge sections including eight bridges of 1,635 meters in total length, and highway sections of 4,273 meters in total length. In parallel with the main tunnel, an evacuation tunnel will be constructed. The ventilation system is a jet-fan longitudinal ventilation system with an intermediate ventilation adit and three electrostatic precipitators. At the south tunnel portal, a tunnel operation building will be constructed together with a 110/22kV substation from which the required power for tunnel operation will be supplied.
