Community shapes refined design for Medlow Bath Highway upgrade

27 July 2021

Revised designs for upgrades to the Great Western Highway at Medlow Bath have been released, following detailed feedback from the Blue Mountains community.

Liberal Senator for Western Sydney, Senator the Hon Marise Payne, said the broader $4.53 billion upgrade of the Great Western Highway between Katoomba and Lithgow would enhance road safety, decrease congestion, and support over 2,500 jobs.

“Completing the duplication of the Great Western Highway west of Katoomba is a major, long-term investment in the Blue Mountains which builds on our government’s track record of improving road infrastructure from Lapstone to Mt Victoria,” Senator Payne said.

“The updated design, which follows community consultation facilitated by Transport for New South Wales, includes installing traffic lights at Bellevue Crescent to provide safer access for vehicles turning on and off the Great Western Highway and will further moderate the speed of vehicles moving through Medlow Bath.

“Importantly, the revised designs include dedicated turning lanes into Bellevue Crescent.”

NSW Minister for Regional Transport and Roads Paul Toole said Transport for NSW was also seeking community feedback on an alternative option for the intersection, which would include an intersection adjacent to the United Service Station, with a connection to Bellevue Crescent.

“We want to limit the impact on property, so we’re also putting forward a new design that would turn the existing intersection into a cul-de-sac and provide a new safe, signalised intersection and U-turn facility for motorists travelling east-bound on the Highway,” Mr Toole said.

“We’ve also heard the community loud and clear on safety and local amenity, which is why we’ve including new landscaping to improve separation between the shared pathway and the highway, and create a better look and feel for Medlow Bath.

“Listening to the community and acting on feedback has been vital in helping us get this right and we will continue to work with the community every step of the way.”

Community members are invited to view the Review of Environmental Factors which outlines the results of a comprehensive assessment of all potential impacts from the upgrade.

Construction is expected to start at Medlow Bath by the end of 2022.
