7NEWS Australia published this video item, entitled “The Sydney Metro tunnel under Sydney Harbour | 7NEWS” – below is their description.
Crossing the harbour in record time – the new underwater rail line will do just that.
It’s a Sydney Metro tunnel 40 metres below the surface, running between Barangaroo and North Sydney. Track-laying is now complete. 2,400 railway sleepers have been installed.
It’s a major milestone for the Sydney Metro project on a day of more upheaval for the rail network.
