SICE delivers Rozelle Interchange, now open to traffic

SICE delivers Rozelle Interchange, now open to traffic

The highly anticipated final stage of the WestConnex project, the Rozelle Interchange, officially opened to traffic on 26 November 2023, operating under SICE’s advanced Operations Management Control System (OMCS) solution, SIDERA. Led by Transport for NSW and delivered by John Holland and CPB Contractors (JHCPB) JV, this massive achievement marks a significant milestone in Sydney’s evolving transportation landscape.

The Rozelle Interchange, linking the M4 to the Anzac Bridge and the M8 to the City West Link and Victoria Road, with its more than 24 kilometres of interwoven and overlapping tunnels, will transform travel across Sydney. Long-term, motorists will save time during morning peak hours on a trip between Parramatta and the Sydney CBD.

SICE, a key player in the success of the project, was entrusted with the design, supply, testing, and commissioning of its in-house solution, SIDERA, and associated hardware for the Operations and Management Control System (OMCS) and seamlessly integrating it into the existing Integrated OMCS (IOMCS) which is already overseeing the operational stages of WestConnex (M4 East, M8, and M4-M8 Link). The comprehensive scope encompassed the design and commissioning of various critical Intelligent Transport Systems (ITS) subsystems such as Driver Advisory Signage, Vehicle Detection, CCTV, AVID, Phones, Tunnel Closure and Over Height Detection, and Motorway Network Communications. Furthermore, as part of this project, SICE has configured and provided over 800 cameras, over 900 phones and the whole TMCS and PMCS communication networks (around 600 network devices).

The Rozelle Interchange is now integrated into the broader WestConnex tunnels, thanks to SICE’s advanced IOMCS underpinned by SIDERA. This integration ensures safety and efficiency, streamlining daily operations and maintenance across the entire infrastructure. The IOMCS solution empowers traffic control room operators to manage all WestConnex tunnels from a unified, fully integrated control room, resulting in reduced operating costs and heightened levels of safety and efficiency. This integration has been one of the most complex activities of the project, where SICE has had to integrate Rozelle Interchange OMCS into the operational WestConnex IOMCS.

Manuel Gonzalez Arrojo, SICE ANZ Managing Director, emphasises, “SICE’s expertise has played a pivotal role in the successful implementation of the project, with a team of over 120 dedicated engineers from Spain and Australia navigating the project’s significant technical challenges. This new landmark stands as a testament to the collaborative efforts of SICE, JHCPB, TfNSW, WCX, and all stakeholders involved in enhancing Sydney’s motorway network for the generations to come and improve the quality of life for local communities”.

Beyond the technical achievements, SICE takes pride in the diversity of its talented team on this project, with key leadership roles bringing invaluable perspectives. This exemplifies our dedication to gender equality and diversity and sets a positive example for the transformative industry’s future.
