Since then, there has been extensive community engagement, geotechnical testing, field studies and market sounding with the finance and construction industries. This project update provides an overview of how the proposed design has evolved, incorporating feedback from community and stakeholder groups over the past year. Roads and Maritime Services want to hear what you think about where we are up to. We will shortly commence community engagement on the design presented in this project update. Once we have heard your feedback, we will continue to refine the design. The NSW Government will then progress Aerial view of Birchgrove this refined design through the planning assessment process.

Assessor's Summary of Significance: The building of the Sydney Harbour Bridge was a major event in Australia's history, representing a pivotal step in the development of modern Sydney and one of Australia’s most important cities. The bridge is significant as a symbol of the aspirations of the nation, a focus for the optimistic forecast of a better future following the Great Depression. With the construction of the Sydney Harbour Bridge, Australia was felt to have truly joined the modern age, and the bridge was significant in fostering a sense of collective national pride in the achievement.

  • Arcure Continues Its International Expansion by Equipping the Westconnex Motorway, Mega-Construction Site in Sydney
    Paris, the 11th of October 2019 Arcure continues its international expansion by equipping the WestConnex Motorway, mega-construction site in Sydney Specializing in artificial intelligence (AI) applied to image processing in the industrial world, Arcure has been selected by the consortium Lendlease Samsung Bouygues Joint Venture (LSBJV) to equip machines working on the WestConnex M4-M5 Link project in Sydney with Blaxtair®, the reference solution for pedestrian protection around industrial vehicles. « WestConnex is one of the largest road infrastructure projects in Australia. Having equipped industrial sites in the Greater Paris area and also supplied Blaxtair® pedestrian detection systems for mobile plant on parts of the London underground expansion project, we are proud to work on the safety element of this huge undertaking. This new collaboration on an infrastructure operation of this size testifies to the relevance of the Blaxtair® solution and has spurred us to actively seek further international projects and opportunities », Franck Gayraud, CEO and co-founder of Arcure. Blaxtair® is the result of a collaboration between Arcure and the CEA's (note to editors: in France, the CEA is the Alternative Energies and Atomic Energy Commission) research laboratories and is considered the industry-leading, embedded detection system. This innovative 3D camera detects obstacles around mobile plant and/or materials handling equipment. Thanks to AI, Blaxtair® differentiates between pedestrians in the designated detection zone and objects/obstacles, thus helping to avoid pedestrian collisions. Its unique technology will warn a driver in case of danger, avoiding unnecessary alarms and untimely stops. The adaptability and responsiveness offered by the Blaxtair® system allows mobile plant to be used with minimal risk to pedestrians on industrial sites with the most demanding operating conditions.

  • Sydney Harbour Birdge Southern Toll
    Appendix C Consultation strategy and stakeholder correspondence Community and communications plan Sydney Harbour Bridge southern toll plaza precinct upgrade Bridge Approaches Sydney Harbour Bridge Southern toll plaza precinct upgrade Communications plan October 2012 Draft 4 – internal working document __________________________________________________________ 1. Project overview Roads and Maritime Services (RMS) proposes to realign and resurface the traffic lanes on the Bradfield Highway, on the southern approaches to the Sydney Harbour Bridge, (the proposal). The proposal is aimed at simplifying traffic movements and reducing road safety hazards for the quarter of a million people including 27,000 bus passengers who use road transport to cross the Sydney Harbour Bridge daily. The proposal would involve removal of the toll booths from the southern approaches to the Sydney Harbour Bridge where tolling operations have been undertaken since the bridge was opened to traffic in 1932. Electronic tolling became fully operational in 2009, which means the additional road lanes which facilitated manual tolling are no longer required. The proposal would also involve upgrading the traffic management systems to ensure greater efficiencies in traffic management. This proposal has been made possible by a separate project to modernise and relocate the bridge tolling system to a location north of the bridge, which was determined under a separate environmental assessment (RMS, 2012). The proposal presents an opportunity to upgrade and rationalise the southern toll plaza precinct to simplify traffic movement on the bridge, improve operational flexibility, reduce road safety hazards, and to realise cost efficiencies for RMS. Simplifying and rationalising the lanes would also support separate initiatives to improve bus travel-time reliability to Wynyard in the northern Sydney central business district (CBD).

  • A Realistic Method of Strengthening Iron Cove Bridge
    Strengthening of Bridge over Iron Cove, Sydney NSW - A Realistic Design Load Wije Ariyaratne, B.Sc (Eng), M.Eng.Sc, Grad Dip Bus, FIE Aust. Manager Bridge Engineering, Bridge Section, RTA Operations Parvez Shah, B.Sc (Eng), M.Eng (Struc.), Grad Dip Bus, MIE Aust. Manager, Bridge Evaluation and Assessment, Bridge Section, RTA Operations Henry Fok, B.Sc (Eng), M.E Eng.Sc, MIStructE Project Engineer, Bridge Evaluation and Assessment, Bridge Section, RTA Operations ABSTRACT The bridge over Iron Cove on Victoria Road consists of seven steel truss spans of 52m and four continuous plate girder approach spans of 18m. The bridge has a carriageway width of 13.7m between kerbs and it carries four lanes of traffic. In addition it has one 3.1m wide dedicated BUS lane on the southern side and one footway on the northern side. The bridge is on a major arterial road and carries B-Doubles. The bridge was built in 1955 when the design load was MS18 (33t), which was significantly less than current legal loads (eg 42.5t Semi- Trailers and 62.5t B-Doubles). Generally, strengthening of bridges is carried out in accordance with the 1996 AUSTROADS Bridge Design Code (’96 ABDC). However, because of the earlier studies conducted in assessing the bridge, it was evident that strengthening the bridge as per ’96 ABDC would have been exceptionally expensive. In addition, it was thought that the bridge would not experience the live loads stipulated in the ’96 ABDC for the next 50 years or during its expected life. Therefore, the Bridge Section proposed a realistic method of determining live loads for strengthening the bridge for legal loads based on the current legal loads experienced by the bridge, the probability of multiple presences of legal loads and the predicted future growth of legal loads over the route.

  • Bridge Aesthetics
    Bridge Aesthetics Design guideline to improve the appearance of bridges in NSW Centre for Urban Design | February 2019 The curved bridge over the Woronora River with its pedestrian and bicycle foot bridge hung below the road deck and the remodelling of its foreshores, fits in with the river, topography and sandstone and bush landscape of Sutherland. With its ten spans, 30 metre high piers, and approaches cut into the opposing hillsides the bridge produces a sweeping, dramatic and elegant built form. Acknowledgments This document has been prepared by the TfNSW Centre for Urban Design with input from Bridge Section, Environmental Branch, and the Government Architects.
