A $51 million upgrade to one of the Hills’ busiest roads has moved a step closer, with The Hills Shire Council awarding the tender for the Annangrove Road Upgrade.
The project will transform a 1.9km stretch of Annangrove Road in Rouse Hill from a rural road into a four-lane sub-arterial road, running from Windsor Road to Edwards Road. Traffic volumes are approaching 20,000 vehicles a day, and the Hills Shire is one of the fastest-growing regions in the country, putting real pressure on infrastructure that hasn’t kept pace.
The upgrade is jointly funded by the NSW Government’s Accelerated Infrastructure Fund, the State Infrastructure Contribution program, and The Hills Shire Council. The state government has committed $31.4 million of the total through the AIF and SIC programs, with council covering the remainder.
Annangrove Road services a number of fast-growing communities across North West Sydney, including the Box Hill precinct, and the finished project is expected to directly benefit more than 13,000 households.
Once complete, the road will carry two lanes in each direction separated by a central median, replacing the existing rural single-carriageway layout. Bus services running through Box Hill, Box Hill Industrial and North Kellyville should also see improved conditions.
The scope of the works is broad. Council and its contractor will widen the road to four lanes with a central median, install new traffic signals, and add kerb and guttering along with median and traffic islands. Underground and overhead services — water, sewer, power and telecommunications — will need to be adjusted or relocated to make way for the new road.
A shared path and footpaths will be built alongside new stormwater drainage and water-quality treatment infrastructure, and the existing power poles will come down in favour of new street lighting. Landscaping and fencing works round out the plan, along with ongoing traffic management for the life of the project.
Construction is expected to start in late 2026, with completion scheduled for 2029, weather and site conditions permitting. Given the scale of the works, council is warning residents and commuters to brace for significant disruption.
Traffic conditions and routes are likely to shift throughout construction, and motorists are being urged to plan ahead and build extra time into their journeys. Council says it will work with its contractor to keep disruption to a minimum and will keep the community updated as traffic changes roll out.
