Designing the Concord Road Bridge

Sydney, Australia - Arcadis is helping Sydney commuters avoid local roads and improve traffic conditions with its work on the Concord Road Interchange as part of the WestConnex New M4 project.

62.5 m

maximum span

213 m

total length

The project hit a significant milestone recently when steel girders were erected over Concord Road Bridge crossing the M4. Six of the twelve twin steel girders are now installed, comprising spans 3, 4 and 5. The permanent substructure is complete and the girders for Spans 1 and 2 will be constructed with the aid of temporary steel piers, one of which will sit within the current M4.

The bridge will connect Concord Road southbound to the New M4 Motorway westbound, which will allow commuters to avoid Parramatta Road and two intersections, not only helping to make their commute faster but also removing more cars off Parramatta Road. 

An impressive engineering feat, the Concord Road Bridge will include both horizontal and vertical curves in its design. The horizontal curve has a radius of approximately 80 metres, requiring innovative designs to maintain strength and safety during construction and when operational.



Key bridge stats include:
• 5 continuous spans with a 62.5 metre maximum span and a total length of 213 metres
• It crosses the M4 Motorway and Concord Road
• The superstructure consists of twin steel trough girder composite with an in-situ deck slab
• To achieve the maximum span while still providing clearance over Concord Road, the steel girders are haunched over piers 1 and 2

Arcadis were appointed to provide civil design services for the WestConnex New M4 project in a joint venture with AECOM. The services provided include geometry and road engineering, pavement design, flood assessment and drainage design, traffic engineering services, lighting design, utilities coordination and structural design of the bridges, retaining walls, cut and cover tunnels and buildings.
