Inauguration of the M4 East tunnel between Parramata and Homebush

Last month, the new tunnel on Sydney's M4 motorway linking the suburbs of Homebush and Haberfield, was opened to traffic. This tunnel, consisting of twin tunnels with three lanes in each direction and a total length of 6.5km, is an extension of the M4 motorway between Parramatta and Homebush, as a part of the WestConnex plan – Australia's largest transport infrastructure project. It has created up to 4,000 new jobs, and will help to decongest traffic in Sydney and reduce surface truck traffic.

As part of this ambitious project, SICE has implemented its renowned Operations & Management Software (OMCS) SIDERA platform, which has seen excellent results in the management of more than 2,500km of roads and more than 300km of tunnels around the world. One of the unique features of this project is the implementation of a communications protocol that will be used in all WestConnex branches to control each section from a single control centre, called the Integrated OMCS (IOMCS).

In 2020, the M5N section of WestConnex will also be inaugurated which will connect St. Peters with Beverly Hills, and in 2023 a final section linking the M4 and M5.

For the development of WestConnex, SICE has worked to integrate equipment previously installed in the M4 West section (which is not operated by SICE) into our SIDERA Operation & Management Software (OMCS). The integration of this equipment in SIDERA will allow for a centralized management of all the sections via the IOMCS.

In addition to the development of the control software, SICE’s team has worked against the clock to implement the rest of the tunnel’s control systems in its scope, such as: the communications network, PLCs, vehicle detection systems, signalling, emergency telephones and video surveillance (CCTV), amongst others. After the opening of the tunnel, SICE will continue to fine-tune the system, adjust it as required, and perform maintenance until 2026.

Since the first project began in February 2016, SICE’s team has grown exponentially to meet the installation and commissioning requirements of the project, as well as creating unique tools and solutions in response to the needs of a project, such as WestConnex.
