The Federal Highway was declared a National Highway in NSW in 1974 and in the ACT in 1994. It is an important link between Sydney and Canberra with all approved road activities fully funded by the Federal Government. This environmental impact statement (EIS) considers a proposal to construct dual carriageways between Stirling Avenue in the ACT and the Sutton interchange in NSW. The 10 kilometre section of highway is managed by the Department of Urban Services within the ACT and by the Roads and Traffic Authority in New South Wales.
