Sydney Metro construction works are well underway with major excavation creating the underground platforms for the Central Station.
The excavation has reached 8m below the station with about 4000 tonnes of material excavated every week.
A new concrete traffic deck allows more than 40 trucks to access the site every day and remove the materials.
A huge 135 tonne crane installed in July will soon be used to install steel modules for a new temporary pedestrian pathway.
To enable ongoing excavation, changes are being made to some of the pedestrian tunnels below Central Station.
New pedestrian pathways will be available to ensure the 270,000 daily customers can continue to make their way around the station.
