And will commence planning upgrades at:

  • Katoomba to Medlow Bath

  • Forty Bends to South Bowenfels.

A tunnel at Blackheath is also planned. The design of the tunnel includes three possible portal options: 

  • A northern portal next to the Mount Boyce Heavy Vehicle Safety Station
  • A short southern tunnel portal option located in Sutton Park, and
  • A long southern tunnel portal option south of Evans Lookout Road.

The NSW Government is also investigating an 11-kilometre tunnel linking the two tunnels (previously planned to be separate) at Blackheath and Mount Victoria.

Detailed Planning
Great Western Highway Upgrade - Blackheath to Little Hartley

In March 2019, the NSW Government announced that it would duplicate the Great Western Highway, from Katoomba to Lithgow over the next 10 years.

The Blackheath to Little Hartley section involves construction of a four-lane motorway, which includes a Mount Victoria Bypass.

A central component of this highway upgrade is a proposed 11-kilometre tunnel which would begin at south of Evans Lookout Road, in Blackheath and end at the base of Mount Victoria, at Little Hartley. If approved, it would be the longest road tunnel in Australia.
