    The Northern Road & Bringelly Road Upgrade - Stage 2

    Stage 2 Upgrade of The Northern Road and Bringelly Road involves both major roads being widened from generally two traffic lanes to become four-lane roads together with kerbside bus lanes, plus a wide central median to allow for future widening to six main traffic lanes. There will also be a 3m-wide shared pedestrian/cyclist path, new slip lanes and upgrades of intersecting streets.

    Our scope includes property adjustments and extensive relocations of gas, electricity, water, telecommunications and other utilities. A significant additional contract was awarded to the Lendlease team by Sydney Water to install a new Trunk Main.

    A key section of the Western Sydney Infrastructure Plan, this contract comprises three components that are being delivered as a single project to reduce the impact on local residents and traffic:

    1. The Northern Road Upgrade - Stage 2: An 11.3km upgrade of The Northern Road, between Peter Brock Drive at Oran Park and Mersey Road at Bringelly
    2. Bringelly Road Upgrade - Stage 2: Upgrading 4.3km of Bringelly Road, between King Street and The Northern Road
    3. Grade-separated Interchange: Replacing the intersection of The Northern Road and Bringelly Road with an underpass for The Northern Road, allowing traffic flow along both major roads without the need to stop at traffic lights.

    Both of these major roads are being widened from generally two traffic lanes to become four-lane roads together with kerbside bus lanes, plus a wide central median to allow for future widening to six main traffic lanes. There will also be a 3m-wide shared pedestrian/cyclist path, new slip lanes and upgrades of intersecting streets.

    Bringelly Road remains on its existing alignment, while a re-aligned section of The Northern Road is being diverted from its current route. To create the new underpass, our team placed 2,600m3 of concrete in a single continuous pour to construct one of the largest voided-slab, post-tensioned bridges ever built in Australia. At 57m wide, it is wider than the 45m-wide Sydney Harbour Bridge.

    The existing South Creek bridge will be demolished and replaced by two new 38m-long bridges over South Creek. Other aspects include indented bus bays on both sides of Bringelly Road, plus construction of a new car park and service road for Rossmore Public School.

    Our scope includes property adjustments and extensive relocations of gas, electricity, water, telecommunications and other utilities. A significant additional contract was awarded to theteam to divert the Sydney Water Main servicing this growing area.
