The Roads and Traffic Authority of New South Wales (RTA) is proposing to upgrade a 3.8 kilometre section of the Great Western Highway between the Station Street, Woodford and Ferguson Avenue, Hazelbrook. The existing single carriageway would be upgraded to a dual carriageway with two lanes in each direction, improving road conditions and increasing safety. Most of the proposed upgrade would be located within the existing road corridor to minimise potential impacts on the environment and private property.
