The tunnel between St Vincent’s and the Royal Victorian Eye and Ear Hospital was built to support a planned rationalisation of services by the two hospitals.
It stretches 164 metres under Victoria Parade and lies 10 metres below the surface.
It was built with the aid of excavating equipment similar to that used for the Melbourne underground rail loop.
The project took about ten years to come to fruition, with hospital architects holding preliminary discussions in 1973, excavation beginning in September 1979 and its official opening held on 18 April 1983.
Today the tunnel is used to transfer stable patients, equipment and personnel; the tunnel has also been used by film and television crews for music videos, TV shows and feature films.
