In 1993, a system of arterial route numbering in the Sydney metropolitan area was introduced called Metroads. These replaced National Routes and Highways and many State Routes throughout the Sydney region. Metroads are divided up into two types - radial Metroads, which connect the outer suburbs with the city centre of Sydney; and circumferential Metroads, which are major by-pass routes around the Metropolitan area.
There are now nine Metroads in Sydney numbered from 1 to 10 (Metroad 8 has been reserved for future use - my guess is that it will be used for the much needed and long awaited Western Sydney Orbital freeway).
The original Metroad system only had 6 routes - 1, 2, 3, 4, 5 and 7. Metroad 9 was added in 1997; Metroad 10 in 1998 and Metroad 6 in 1999. The Metroad system is in a continual process of refinement; routes are continually expanding and contracting and are often being adjusted.
Below is a map of Sydney's Metroad system, showing all Metroads as they stood in January 2003. Freeway portions of the Metroads are in green. The National Routes and Highways and State Routes that radial Metroads meet up with on the metropolitan outskirts are also shown.
