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.
