Arcadis’ road engineering team in Sydney devised innovative civil engineering solutions to overcome challenges and complete designs parallel to the planning approval process.
By reducing travel times and improving road capacity, the WestConnex project will pave the way for a more efficient road experience for the people of Sydney.

With Sydney’s population estimated to increase by 1.5 million over the next 20 years, with much of that growth likely to occur in Western Sydney, the NSW government needed to develop new road infrastructure to accommodate the swelling demand for transport and road use on Sydney’s motorways.
In association with AECOM, Arcadis was responsible for civil, structural and building design of the 5.5km extension of the M4 Motorway from Homebush Bay Drive in Homebush to Wattle Street in Haberfield. This component of the project included a 3.5km tunnel and 1km of above ground surface works with two new three-lane carriageways beneath Paramatta Road and major road bridges including a steel bridge over the existing M4 motorway and bridges at Homebush Bay Drive and the Concord Road Interchange.
WestConnex is a critical part of a broader plan to get Sydney, and Australia, moving again and is expected to deliver significant benefits to the thousands of people who rely on the roads in Sydney and Western Sydney. Travel times between Parramatta and Sydney’s Kingsford Smith Airport will be reduced by up to 40 minutes while bus travel times between the Inner West and the city will be halved. Furthermore, capacity on the M5 East corridor will be doubled, 52 sets of traffic lights will be bypassed and an estimated 4,000 trucks a day will be removed from Parramatta Road, routing them underground.
