A program of borehole drilling is being conducted at over 50 locations along the proposed Cross River Rail corridor.
Borehole drilling in the inner-city for the new Albert Street station, the first rail station to be built in the CBD in 120 years, includes a 125-mm borehole drilled to a depth of 40 metres below the road surface.
The deepest hole drilled to date was at Kangaroo Point and went 66 metres down.
These geotechnical investigations are critical to inform the construction and alignment of the new station.
