Route Overview:

The Federal Hwy was constructed to serve Sydney-Canberra traffic in the 1930's and continues north through NSW to the Hume Hwy near Goulburn. It has been progressively upgraded since the 1970's and now is entirely dual carriageway. Within the ACT there is one grade-separated interchange at Majura Rd (Alt-23) and Horse Park Dr. Duplication of the Federal Hwy was begun in the 1990's and completed in December 2002 when the last section between Antill St and the NSW Border was duplicated. The short ACT section was initially opened to traffic in July 1931, previous access to the Canberra being via Tarago or Gunning.

This route used to be a National Route until 1974, when it was proclaimed a National Highway. Signage on the ground took a long long time to reflect this change and while all green direction signs now show the green and gold shield, there are still 2 remaining black and white trailblazers, dating from the 1980's.
