    Pacific Highway Upgrade: Warrell Creek - Nambucca Heads

    ACCIONA Infrastructure as part of the Pacifico Joint Venture, is responsible for the design and construction of the $550 million Pacific Highway Upgrade between Warrell Creek and Nambucca Heads, in New South Wales.

    The upgrade between Warrell Creek and Nambucca Heads involves:

    • Design and construction of 19.5km of new dual carriageway road.
    • Two grade separated interchanges at Warrell Creek and Bald Hill Road, south of Macksville.
    • Longitudinal bridges across Upper Warrell Creek, Williamson Creek, Warrell Creek, Nambucca River floodplain and Nambucca River.
    • Overbridges on Rosewood Road, Albert Drive, Scotts Heads Quarry access road, Bald Hill Road, Old Coast Road South, Mattick Road and Old Coast Road North and an underpass at Cockburns Lane.
    • Pacifico is working with Roads and Maritime Services (RMS) to develop and implement innovative and efficient design solutions which will reduce the overall construction and operations budget.


    The project is part of the larger Warrell Creek to Urunga Pacific Highway upgrade approved in July 2011 and is jointly funded by the state and federal governments.

    Once complete the upgrade will improve road safety and relieve seasonal traffic congestion.


    Pacifico March 2017 update

    At the beginning of autumn 2017 almost all earthworks on the project have been completed, girders are in place on the two main bridges, two overpasses have been opened and paving and asphalting has commenced along the new highway.

    On the Nambucca River bridge all girders and pre cast concrete floor panels are now installed. The bridge deck is being built, steel reinforcing for the deck construction over the river has started and the deck pour is 60 per cent completed.

    The production of all precast girders finalised in late 2016 and the pre-cast facility decommissioned in readiness for its relocation to another Pacifico project further north.

    The new Mattick Road bridge was opened to traffic before Christmas and the Albert Drive bridge opened in February. The Bald Hill Road temporary deviation is open and traffic is travelling over the new Bald Hill bridge.

    Final girders have been lifted into place on Lower Warrell Creek bridge and on the project’s most northern bridge located on Old Coast Road. The pre cast floor panels are being installed and work will start on the reinforcement of the decks. The central piers are complete on the new Upper Warrell Creek bridge and piling continues.

    Earthworks continue at the North Facing Ramps. Excavation of the material at the railway underpass is complete and the footings and walls are being poured.

    The southern concrete batch plant and the asphalt batch plant have commenced operation with mainline asphalting under way near Cockburns Lane and concrete paving moving south from the Nambucca River floodplain toward Bald Hill.

    A five kilometre section of plain concrete pavement north of Jacks Ridge Road is almost complete and concrete shoulder work along the mainline in the northern section of the new highway will be finalised soon allowing finishing work to start in those areas.
