Rouse Hill locals have been waiting a long time for this one. After years of watching Annangrove Road strain under traffic it was never built for, The Hills Shire Council has finally awarded the tender for a $51 million upgrade that will turn a 1.9km stretch of the road, between Windsor Road and Edwards Road, into a proper four-lane route with two lanes running in each direction.
If you’ve driven Annangrove Road lately, you already know why this matters. Traffic on the road is nudging close to 20,000 vehicles a day, a figure that keeps rising as new housing fills in around Rouse Hill, Box Hill and the wider north-west. The Hills Shire is growing faster than almost anywhere else in Australia, and roads like this one have been struggling to keep up.
The project has been funded through a combination of sources: $31.4 million from the NSW Government via the Accelerated Infrastructure Fund and State Infrastructure Contribution programs, topped up by The Hills Shire Council. Once finished, the upgrade is expected to directly benefit more than 13,000 households, and should also make life easier for commuters relying on buses through Box Hill, Box Hill Industrial and North Kellyville.
The finished road will look very different from what’s there now. Alongside the extra lanes and a central median, the works will bring new traffic signals, proper kerb and guttering, and median and traffic islands. Behind the scenes, crews will need to relocate water, sewer, power and telecommunications infrastructure to clear the way, while above ground the project includes a new shared path and footpaths for walkers and cyclists, upgraded stormwater drainage and water-quality treatment systems, and a switch from old power poles to new street lighting. Landscaping, fencing and ongoing traffic management round out the build.
None of this happens overnight, though. Construction isn’t due to start until late 2026 and is expected to run through to 2029, depending on the weather. That’s a long stretch of roadworks for locals to live with, and council has been upfront that getting there will mean real disruption along the way — changed traffic conditions, shifting routes and longer trips for anyone using Annangrove Road regularly.
Council and its contractor say they’ll try to keep that disruption to a minimum and will keep the community posted as work progresses, but for now, the message to residents is simple: plan ahead, allow extra time, and get ready for a road that’s finally being built for the suburb it serves.
