List of road routes in New South Wales


Road routes in New South Wales assist drivers navigating roads in urban, rural, and scenic areas of the state. Today, all numbered routes in the state are allocated a letter in addition to a one- or -two digit number, with 'M' routes denoting motorways, 'A' routes denoting routes of national significance, and 'B' routes denoting routes of state significance. The route system includes the officially designated highways, urban and intercity motorways and arterial roads, and important cross-state roads that have not been declared highways.

History

Route numbers have been allocated to NSW roads since 1955. National Route 1 was one of the best known numbered national routes, likely because of its fame for circumnavigating the continent. The insignia of national routes was a five-sided black and white shield, chosen as it is the shape of the Australian national coat of arms.
To supplement the national route number system, three ring roads were introduced to Sydney in 1964. These were numbered 1, 3 and 5, with relatively increasing radii. While they were officially decommissioned in 1974, some old ring road 3 signs remained posted into the 1980s, and ring road 1 signs into the 1990s.
In 1973, a system of freeway numbering was introduced to the state to complement the national routes and ring roads. The shields were replicas of the red, white and blue U.S. Interstate Highway shields, and were numbered F1 to F8:
Most of these routes were replaced with other numbers over the decades, and by the 1990s, only the F1, F3 and F6 were still marked as such, with simpler, green-on-white shields. None of these shields remain, but the F3 and F6 are still usually called by those names.
In 1974, the National Highway network was defined, which in New South Wales included the Hume Highway, Federal Highway, Barton Highway, Sydney-Newcastle Freeway and New England Highway. National highways were marked with the same shield as the national routes, except for their green and gold colour and the word 'national' added across the top.
Also in 1974, the three ring roads, 1, 3 and 5, were decommissioned and replaced by new State Routes, which had the same shields as the new freeways but without the red crest. Scores of other State Routes were also designated across New South Wales, marking out urban arterial routes and secondary rural highways. They were allocated as follows:
In 1993, Sydney's Metroad system was introduced, with its prominent, blue-on-white hexagonal shields. There were initially six metroads: Metroad 1 replaced National Route 1 within the metropolitan area, Metroad 2 replaced parts of State Routes 28 and 30, Metroad 3 replaced State Route 33, Metroad 4 replaced the F4 Freeway and the metropolitan part of National Route 32, Metroad 5 replaced part of the metropolitan part of National Highway 31 and Metroad 7 replaced State Route 77. Later, Metroad 6 replaced State Route 45, Metroad 9 replaced the metropolitan part of State Route 69 and Metroad 10 replaced State Route 14 south of Mona Vale. There was never a Metroad 8 as Alpha Numerics came before the.
In 2013, the state replaced its entire system of State Routes, National Routes, National Highways and Metroads with an alphanumeric route numbering system. All numbered routes are allocated a letter in addition to its number, with 'M' routes denoting motorways, 'A' routes denoting routes of national significance, and 'B' routes denoting routes of state significance. Instead of shields, the route numbers are displayed as yellow text on green rectangular background outlined in white. The changeover to alphanumeric routes was announced from March 2013 and signs were updated throughout 2013, either by removing old "shield" coverplates installed on newer signs, or installing new alphanumeric coverplates on old shielded signs. In 2020, the styling of the markers was modified to remove the white border, aligning with all other states except the ACT.

Future road routes

F6 Extension - In 2019, the New South Wales Government announced it would rename the northern extension of the Princes Motorway, between Arncliffe and Kogarah to the "M6 Motorway". No announcement has yet been made on whether the A6 will be renumbered to avoid duplicate numbers.
- Westren Sydney Airport Motorway.
