Editing Route number (section)

====State Routes====
Important urban and inter-regional routes not covered by the National Highway or National Route systems are marked under the State Route system. They can be recognised by blue shield markers. They were practically adopted in all states by the end of the 1980s, and in some states, some less important National Routes were downgraded to State Routes. Each state has or had its own numbering scheme, but do not duplicate National Route numbers in the same state, or nearby routes in another state.<ref name=NAASRA />
As with the National Routes and National Highways, State Routes are being phased out in most states and territories in favour of alphanumeric routes.<ref name=RMS/><ref name=Queensland/><ref name="MRWA signs" /><ref name="RMS alpha QandA" /> However, despite the fact that Victoria has fully adopted alphanumeric routes in regional areas, state route numbers are still used extensively within the city of Melbourne as a part of its [[List of old road routes in Victoria|Metropolitan Route Numbering Scheme]].<ref name="VicRoads signs" />
