WestConnex New M5, Australia

Aurecon provides key engineering design services for the WestConnex masterplan

WestConnex New M5 is a key element of the WestConnex master plan for Sydney. It duplicates the existing heavily congested M5 tunnel, and, once completed, will separate city bound and airport bound traffic to ultimately ease congestion and connect communities.

Aurecon, in partnership with Jacobs, will provide key engineering design services across design management, civil, tunnel, road, bridge, cut & cover, drainage, HV &LV, lighting, M&E spatial, water treatment, environmental, traffic modelling and buildings services for the CPB Dragados Samsung Joint Venture (CDSJV).

The Aurecon Intelligent Transport Systems (ITS) team in particular are tasked with delivering the designs for all ITS equipment deployed for the project. This includes electronic signs (Tunnel Message Signs, Integrated Speed Limit and Lane Usage Signs, Variable Message Signs), traffic detection and monitoring devices (Vehicle Detection Loops, Closed Circuit Television Cameras) and tunnel closure devices (Overheight Detection, Moveable Physical Barriers). The designs also include ITS communications cableway routes and fibre topologies.

At a glance, the WestConnex New M5 consists of:

  • 9 km of twin road tunnels from King Georges Road Interchange at Bexley, in the west, to the new four level St Peters Interchange at St Peters in the east
  • Two primary tunnel cross sections for two lanes and four lanes
  • A new four level St Peters Interchange that includes complex interweaving of on and off ramps that require numerous large box girder bridges
  • Ventilation facilities located at the western portal (at Kingsgrove and Arncliffe) and at the eastern portal (at St Peters)

Overall, the wider WestConnex project will directly benefit millions of people every day through safer connections to communities, and more efficient travel times for freight and cars.

The project is expected to be open to traffic in 2020.
