    Bridge over Clarence River at Harwood

    ACCIONA as part of Acciona Ferrovial Joint Venture (AFJV), was engaged to design and build the new bridge over the Clarence River at Harwood, located on the Pacific Highway, in New South Wales.

    General information

    Location: Harwood, NSW, Australia

    Our role: Design and construct

    Infrastructure: Design and construction of 1.5km single deck bridge

    Project value: Part of the overall AU$4.36 billion Woolgoolga to Ballina Pacific Highway upgrade

    Completion date: End 2019

    Key Features

    • 1.52 kilometre, 35 span dual carriageway bridge
    • 620 metre length over the river
    • 30 metre vertical clearance above the river
    • 20 metres east of the existing Harwood Bridge
    • 117 marine and land piles
    • 35 piers – 13 in the Clarence River and 22 on land
    • 144 concrete bridge girders weighing up to 168 tonnes each
    • all girders built at on-site precast yard


    The project is part of the larger AU $4.36 billion Woolgoolga to Ballina Pacific Highway upgrade and is jointly funded by the state and federal governments.

    The upgrade will improve road safety, reduce travel times and increase transport efficiency.


    Current Status

    The new bridge over Clarence River at Harwood, designed and constructed by ACCIONA together with Ferrovial, opened to traffic on 5 December 2019 after the sections adjoining the new bridge were completed.

    The new bridge is 1.5 kilometres long and has been designed to retain the much admired heritage of the existing bridge. Its aligned piers and height reflects the height of the existing bridge’s lift bridge. It provides safer, smoother travel for motorists and eliminate the need for highway motorists to stop while the existing bridge is raised for maritime users.

    The contract to design and construct the new bridge was awarded to ACCIONA and Ferrovial joint venture in July 2016 for an estimated AU$250 million (€154 million).

    The new bridge has been constructed from 144 innovative “U” shaped beams that require 30 percent less concrete compared to “T” shaped beams. The beams, each weighing 168 tonnes, were safely installed using complex manoeuvres. A 750 tonne crane operating from a barge on the river was used to install the last 48 beams that make up the bridge.

    The design and construction of the new bridge is part of the Woolgoolga to Ballina Pacific Highway upgrade. The project is jointly funded by the Australian and NSW governments.

    As part of the wider Pacific Highway upgrade, ACCIONA, once again in a consortium with Ferrovial, built a 19.5 kilometre section of road between Warrell Creek and Nambucca Heads. This section of road opened to traffic in 2018.
