Early works for the project have been underway since September 2017. Underground geotechnical investigations (or borehole drilling) will help identify any dirt, rock or other features that may impact tunnelling works or station construction.

A program of geotechnical investigations and borehole drilling is being conducted at over 50 locations along the proposed Cross River Rail corridor.

Our drill rigs will be set up on Albert Street from Sunday 22 April until Friday 27 April. Work will be from 6pm to 6am each day (excluding Anzac Day), weather and construction conditions permitting.

Please note there will be temporary loading zone closure as the drill rig will stay in place throughout the duration of the works, so drivers and pedestrians are advised to exercise caution around the area.

The deepest hole drilled to date was at Kangaroo Point and went 66 metres down.

Borehole rigs have also been drilling in the inner-city for the new Albert Street station, the first rail station to be built in the CBD in 120 years. This work includes a 125-mm borehole drilled to a depth of 40 metres below the road surface.

These geotechnical investigations are critical to inform the construction and alignment of the new station.
