The Federal Highway is a largely motorway standard roadway linking the from the Hume Highway at Yarra, southeast of Goulburn, New South Wales; to Canberra in the Australian Capital Territory. It is designated as the M23 between its northern terminus and Sutton, and then as the A23 from there to its southern terminus. The roadway has a continuous 110 km/h (68 mph) speed limit within New South Wales. Within the Australian Capital Territory the posted speed limit is 100 km/h (62 mph) in rural areas and 80 km/h (50 mph) once it enters the urban area of Canberra. The entire length of the roadway is dual carriageway with 2 lanes in each direction.[2][5]
