It is located {{convert|6|km}} from the town of Maclean at the village of Harwood. It carries the Pacific Highway from the south bank of the Clarence River onto Harwood Island, from where the Highway crosses the Serpentine Channel onto Chatsworth Island then finally crosses the North Channel of the Clarence River via the Mororo Bridge (also a steel truss bridge) to the northern bank. The Harwood Bridge was completed in August 1966, and replaced the last ferry crossing on the state highway system of New South Wales. Prior to the opening of the bridge, the river crossing was provided by three cable-guided ferries operating in parallel. The bridge has a total length of {{convert|888|m}}, consisting of seven steel truss spans of {{convert|43.1|m}} length and twenty-seven steel girder approach spans. The deck carries two lanes of traffic and a footway. One of the steel truss spans is a vertical-lift span, which allows ships to navigate the Clarence River. However, this now occurs infrequently. The Harwood Bridge forms part of a bypass of the town of Maclean and the village of Harwood. It is the longest, and last, in a series of steel truss bridges of a standard design built by the then-Department of Main Roads during the 1950s and 1960s, chiefly across the wide coastal rivers of New South Wales, and mostly on the Pacific Highway. Bridges of the same design were built on the Pacific Highway across the Hunter River at Hexham (1952), the South Channel of the Hunter River at Mayfield (1965, demolished 2009), the Karuah River at Karuah (1957), the Wollamba River as part of the Nabiac bypass (1958, demolished 2004), the Hastings River as part of the Port Macquarie bypass (1961), and the Macleay River at Kempsey (1959). Upgrading of the Pacific Highway between Grafton and Ballina include a second bridge spanning the Clarence River.[4][5] Work started in 2016 and is expected to finish in 2019.[6] See also{{stack|{{portal|Australian roads|New South Wales|Bridges}}}}References1. ^{{cite news |url=http://nla.gov.au/nla.news-article44026442 |title=Ships that pass... |newspaper=The Australian Women's Weekly |volume=34, |issue=17 |location=Australia, Australia |date=21 September 1966 |page=35 |via=National Library of Australia}} 2. ^{{cite news |url=http://nla.gov.au/nla.news-article142049956 |title=LAST FERRY ON STATE HIGHWAY SYSTEM ELIMINATED |newspaper=Western Herald |location=New South Wales, Australia |date=30 September 1966 |page=6 |via=National Library of Australia}} 3. ^{{cite web|title=Harwood Bridge |work=Roads and Traffic Authority |publisher=Government of New South Wales |url=http://www.rta.nsw.gov.au/constructionmaintenance/majorconstructionprojectsregional/northcoast/harwoodbridge.html |accessdate=3 January 2010 |deadurl=yes |archiveurl=https://web.archive.org/web/20091227202129/http://www.rta.nsw.gov.au/constructionmaintenance/majorconstructionprojectsregional/northcoast/harwoodbridge.html |archivedate=27 December 2009 }} 4. ^{{cite web|last1=NSW|first1=Roads and Maritime Services,|title=Bridge over the Clarence River at Harwood|url=http://www.rms.nsw.gov.au/projects/northern-nsw/woolgoolga-to-ballina/bridge-clarence-river-harwood/index.html|website=Roads and Maritime Services|accessdate=3 December 2017|language=en}} 5. ^{{cite web|title=Bridge over Clarence River at Harwood|url=http://acciona.com.au/projects/construction/roads-bridges-and-special-structures/bridge-over-clarence-river-at-harwood/|website=acciona.com.au|accessdate=3 December 2017|language=en-au}} 6. ^{{cite web|title=Bridge over the Clarence River at Harwood|url=http://www.rms.nsw.gov.au/documents/projects/northern-nsw/woolgoolga-to-ballina/w2b-bridge-over-clarence-river-harwood-update-2017-05.pdf|website=Roads and Maritime Services|publisher=Australian Government}} External links
