Australia’s New South Wales government has called for tenders to begin test drilling for Sydney’s planned 23km long northwest rail link. The project includes a 15km long twin-bore tunnelled section between Epping and Kellyville, which will be the city’s longest ever rail tunnel.
“We expect geotechnical drilling to begin by the end of the year, in line with the O’Farrell government’s commitment to start work on the project as soon as possible,” state transport minister Gladys Berejiklian on Friday.
The test drilling will determine below-ground conditions, including rock type and density, along the planned route of the long-awaited rail link between Sydney’s western and northern suburbs.
“Although much of the tunnelling route is expected to be within Hawkesbury sandstone, an ideal tunnelling medium, a detailed geological review is essential before any major works can commence,” Ms Berejiklian said.
The tenders close on July 4.
