Major excavation work is well underway at Central Station to deliver the new Sydney Metro underground platforms.
Work has reached 8 metres 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.
