Port Hedland Harbour Tunnel
The 444th longest tunnel in the world
The Port Hedland Harbour Tunnel is a 1,030-metre-long (3, 380 ft) bored tunnel in Port Hedland, Western Australia. Owned by BHP, the tunnel carries iron ore fines on a conveyor belt from the company's Nelson Point stockyards to a hot briquetted iron plant on Finucane Island, passing under the Port of Port Hedland. The tunnel was constructed by a tunnel boring machine by Transfield and Kumagai Gumi for A$23.19 million.
