Faster, safer travel for the people of Sydney
CPB Contractors worked with the WestConnex Delivery Authority (WDA) to design and construct the M4 Widening, in a joint venture with Rizzani de Eccher Australia.
The M4 Widening has upgraded 7.5km of the M4 motorway in Sydney as part of the first stage of WestConnex, Australia’s biggest urban road project.
Delivery of the M4 Widening brought early benefits for WestConnex around Western Sydney, including easing congestion and improving connectivity to the motorway.
The project involved widening the M4 from three to four lanes in each direction for approximately 7.5km between Church Street, Parramatta and Homebush Bay Drive, Homebush.
The scope also includes widening the Granville viaduct and existing bridges, as well as constructing new access ramps and one new bridge.
The M4 Widening, which was officially opened to traffic in 2017, will connect with the future M4 East tunnel to Haberfield, also to be constructed as part of WestConnex Stage 1.
