The Roads & Traffic Authority (RTA) is responsible for the maintenance and development of the motorways and state roads in New South Wales (NSW). It is overseeing construction of the £280M Cross City Tunnel, £453M Lane Cove Tunnel and £617M Westlink M7 motorways to complete the Sydney Orbital. All projects are privately financed apart from the Westlink M7 project, to which the NSW government is contributing £146M. Connecting the Cross City Tunnel east to join the orbital is the next stage being considered. The environmental impact statement for the project is being drawn up.
