The railway link between Picton - Maldon to Dombarton - Port Kembla was stopped in 1988 after 5 years of construction. Sucessive governments have spent a fortune on "feasibility studies". It may well have been cheaper to finish the railway rather than stop the project.
The "bridge to nowhere" make a fascinating photographic study. On the same day we visited the "mushroom tunnel" at Picton also a disused railway project.
Quoted from Illawarra Mercury "The project was initiated in 1983 by the Wran state government. About $30 million was spent before the Greiner government cancelled it in 1988. About 30km of track, 4km of tunnel, a 500m bridge across the Nepean and Cordeaux rivers, an underpass under the F5 and a number of bridges over roads and rail tracks would still need to be built, but leftover infrastructure is in reasonable condition."
