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 run between Blackheath, south of Evans Lookout Road and Little Hartley at the base of Victoria Pass, bypassing Blackheath and Mount Victoria.
