Windsor Road Upgrade
New South Wales, Australia
The Windsor Road Upgrade is part of the largest urban arterial road upgrade undertaken by any state government. The complete project is a US$315 million upgrade of Windsor and Old Windsor Roads, providing four lanes between Parramatta and McGraths Hill. The north-west is one of Sydney’s fastest growing regions, and the upgrade will have major benefits for both local communities and industry by meeting the existing and future needs of this burgeoning region.
To complete the dual carriageway between the M2 Motorway and Old Windsor Road, the Roads and Traffic Authority of New South Wales formed its second alliance contract, including Maunsell. This North West Connect Alliance was responsible for delivering a 3km section between Roxborough Park Road and Norwest Boulevarde in Baulkham Hills, and a 2.6km section between Acres Road and Old Windsor Road in Kellyville.
The US$78 million project includes the following features:
- Two new twin bridges over Strangers and Caddies Creeks
- Three new signalised intersections and a signalised pedestrian crossing at Baulkham Hills Private Hospital
- Enhanced public transport with bus bays and bus priority at signalised intersections
- US$15 million of utility adjustments
- Extensive landscaping
- An energy dissipation pond to minimise environmental damage to creek banks in Torry Burn Reserve
- Shared pedestrian and cyclist path along the southern side of Windsor Road
- Significantly improved travel times and safety along the road and reduced congestion
Construction began in May 2005, and despite working around existing traffic flows of approximately 40,000 vehicles per day, the project was successfully opened to traffic in July 2006, five months ahead of schedule.
