In addition to the National Highway 1 designation, the freeway at one stage carried the Freeway Route 3 (F3) designation.
This route numbering system, introduced in 1971, was to provide distinctive route numbering and signage for freeways in Sydney and the surrounding areas.
Although the route was never signed with the F3 route marker (the numbering system was removed in the late 1980s), the route is still often referred to as the F3 Freeway, with this title being used not only colloquially but on state and federal government documents and web sites and some road signs.
