In March 2019, the NSW Government announced it would duplicate the Great Western Highway from Katoomba to Lithgow over 10 years. Once complete, the Great Western Highway Upgrade Program (GWHUP) will result in 34 kilometres of four lane divided highway between Katoomba at Rowan Lane and Lithgow / South Bowenfels at Magpie Hollow Road. The GWHUP is split into the eastern, western, and central sections and will be procured through seperate packages of work
The Eastern Section consists of the upgrade of the GWH between Katoomba and Blackheath into a four-lane divided carriageway. The Eastern Section is approximately 7.2 kilometres and is primarily made up of the six-kilometre East package and the 1.2-kilometre Medlow Bath package, which are being procured separately.
The Western Section consists of the upgrade of the GWH between Little Hartley to Lithgow into a four-lane divided carriageway. The Western Section is approximately 14.2 kilometres and is primarily made up of the 11.9-kilometre West package and the 2.3-kilometre Coxs River Road package, which are also being procured separately.
The Central Section commences east of Blackheath to Little Hartley and comprises delivery of a proposed 10.6-kilometre dual carriageway tunnel.
