The M12 Motorway is an integral part of the $4.4 billion Western Sydney Infrastructure Plan. The new motorway will deliver significant travel time reductions and increased travel time reliability to road users and freight operators, by providing a high standard and efficient connection to Western Sydney Airport and connect to Sydney’s motorway network.
Seymour Whyte will deliver a 7.5km dual-carriageway motorway, 11 bridges, cycle and pedestrian paths, networks, intelligent transport systems and green areas.
The project is targeting an ‘Excellent’ infrastructure sustainability rating – with the Infrastructure Sustainability Council – by reusing and recycling 95% of the excavated materials, using 40% of recycled aggregates for the sub-base layers and minimising water use on the site.
The motorway dual carriageway has a wide median to allow for future widening to six lanes; and safety barriers will be placed along the length of the motorway. Emergency stopping bays and emergency crossovers will also be at regular intervals.
The motorway will increase road capacity, reduce congestion, and improve travel times and freight movement in and through Western Sydney.
A shared user path with lighting will provide an active transport link along the motorway and eastward to the M7.
The M12 Central package includes the following bridges:
- Twin bridges over South Creek
- A bridge for Clifton Avenue over the M12 Motorway
- Twin bridges over Kemps Creek
- Twin bridges over Elizabeth Drive near Mamre Road
- Twin bridges over Range Road
- A bridge for the Water Tower Access Road over the M12 Motorway
- A private property access bridge in University of Sydney land.
The works will provide retaining walls near Range Road to limit project impacts and will adjust local roads, including Clifton Avenue and Salisbury Road.
