Northern Tunnel Exhaust Stack
One of the most distinctive features of the Waterview Connection is the Northern Ventilation Stack. It is required to exhaust vehicle emissions from the twin tunnels. Towering 15 metres above road level, elliptical, and on a 20 degree lean.All 20 precast sections are cast with different angles, providing the illusion that the structure is twisting as it rises into the sky.
The northern ventilation building comprises mechanical and electrical equipment and a vent stack located 120 metres away from the tunnel portals.
