Work progressing on Great Western Highway safety upgrade from Hartley Valley to Forty Bends

18 February 2016

Work is ramping up on the $250 million Great Western Highway upgrade between Katoomba and Lithgow with significant progress between Hartley Valley and Forty Bends.

“The Australian and NSW governments are funding this important upgrade to improve safety on the major road corridor linking Sydney to the west of NSW,” a Roads and Maritime Services spokesperson said.

“The safety upgrades between Hartley Valley and Forty Bends include five main intersection upgrades, a new structure above Whites Creek to reduce the risk of black ice formation, new bus bays and road surface improvements.

“During the past six months work has included earthwork, soil stabilisation and asphalting.

“The next stage of work will include asphalting through Hartley Valley and River Lett Hill, concrete paving through Forty Bends to build the road base and building retaining walls at Hartley Village.

“Utilities will also be relocated, new drainage infrastructure installed and driveway adjustments completed to provide safer access for residents.

“The work is on track to be completed in 2017, weather permitting.

“Meanwhile, planning is continuing for the broader upgrade from Katoomba to Lithgow with the Review of Environmental Factors and concept design on display for work on the Great Western Highway between Katoomba and Mount Victoria until Thursday 3 March.

“Motorists are reminded changed traffic conditions are in place along the Great Western Highway.

“From Tuesday 23 February work will be carried out at River Lett Hill to South Bowenfels to install roadside barriers.

“Work hours are from 7am to 6pm on weekdays and 8am to 1pm on Saturdays, weather permitting.

“Lane closures and reduced speed limits will be in place where required for the safety of road users and workers.

“During work hours motorists can expect short delays and should plan ahead their journey.”
