Doing the groundwork for highway upgrade

3 March 2021

A large drilling rig will make its way across the Blue Mountains in the next six months taking soil samples and testing ground water as part of early work on the Katoomba to
Lithgow Great Western Highway upgrade.

Minister for Regional Transport and Roads Paul Toole said the hydrogeological testing was a critical step forward to inform environmental assessments and assist with the design
of tunnel routes and building methods.

"It will be difficult to miss the high visibility vest wearing team accompanying the rig as they start work this week in Blackheath and make their way across the mountain range to
conclude at Little Hartley in August," Mr Toole said.

"These locations have been chosen to help with developing a base line understanding of geology and below surface water flow across the proposed route, so that we can ensure
we deliver an upgrade that enhances the Blue Mountains and preserves its unique and pristine beauty."

"This is a massive and complex project, so we want to take the time to get it right and understand all the environmental, engineering and safety fact ors involved."

Investigation work will be carried out for up to three weeks in each location:

  • Sutton Park, Blackheath
  • Blackheath Gardens, Blackheath
  • Heavy Vehicle Safety Station, Mt Boyce
  • The Explorers Gateway, Mount Victoria
  • Victoria Falls Road, Mount Victoria
  • Montgomery Street, Mount Victoria
  • Matlock Street, Mount Victoria
  • Base of Mount Victoria Pass, Little Hartley.

The majority of work will be carried out between 7am and 6pm on weekdays and from 7am to 2pm on Saturdays, weather permitting.

Access to businesses and residences will be maintained during the work and every effort will be made to minimise the impact of noise from machinery.

Traffic is not expected to be affected by the work, however, motorists should drive to the conditions, allow extra time and follow the direction of signs and traffic control.
