The NSW Roads and Traffic Authority (RTA) has sought approval for a concept plan for a road network connecting employment areas in the Fairfield, Blacktown and Penrith Local Government Areas (LGA) with the M4 and M7 Motorways and Mamre Road. The network is known as the Erskine Park Link Road Network (EPLR Network) in the Western Sydney Employment Hub. The proposed road network is located within the Blacktown and Penrith LGAs but extends to the boundary of Fairfield LGA so as to link the employment lands in that LGA with the roads mentioned.
