Track laying under Sydney Harbour update
Track laying has finished in one of the Sydney Metro railway tunnels under Sydney Harbour, marking a major milestone in the Sydney Metro City & Southwest project.
The 800 metre-section of track in the northbound tunnel is complete after 1,200 railway sleepers and 2,100 tonnes of concrete were installed about 40 metres below the harbour’s surface.
Track laying in the southbound tunnel has reached 30 per cent and will be complete by the end of July.
The tracks in these tunnels connect the future Barangaroo and Victoria Cross (North Sydney) metro stations.
About 800 workers have been fitting out the tunnels.
It will take three minutes to travel between the new Victoria Cross and Barangaroo stations using the tunnels.
