A stretch of Raby Road is set to get an upgrade in coming months.
Camden Council has started concept design work to upgrade the road from the southern section of Emerald Hills to the intersection at Thunderbolt and Epping Forest Drives, Raby.
Camden mayor Theresa Fedeli said the concept design work for the project was due to be complete by early next year.
"Raby Road is a significant east-west link between Camden and Campbelltown City and the areas along the corridor will see growth over the next few years," Cr Fedeli said.
"We're currently the fastest growing area in the country, welcoming more than 100 new residents every week.
"We want to ensure our residents, now and in the future, have high-quality infrastructure and amenity to happily live, work and play in the Camden area."
Camden Council recently awarded the contract to civil engineering and infrastructure design consultancy company, Cardno (NSW/ACT) Pty Ltd.
The design will look to widen the existing two-lane rural road, creating a four-lane, sub-arterial road, with two lanes in each direction.
As part of this process, Cardno will also assess and provide concept design for adjustment of driveway access to private properties along the route and intersection designs.
The upgrade, along approximately 2.5 kilometres of Raby Road, also extends into Campbelltown City.
Campbelltown mayor George Brticevic said the project would ultimately enhance an important connection to the Western Sydney International (Nancy-Bird Walton) Airport.
