Northern Territory
In NT, NR1 has only been fully signposted towards the end of the 1990's as some of the route is still unsealed. The first sections to be signposted were the Victoria and Stuart Highways at the end of the 1980's.
Route changes:
- Original 1955 routing
- Signposted in the late 1980's/early 1990's
- Continuation of route marking from Borroloola to QLD
