  There are four levels of route classification in the Victorian Statewide Route Numbering Scheme (SNRS). The classifcations themselves are based on Austroads guidelines, slightly tweaked by Vicroads to suit Victorian road conditions.
 
   
  M Routes
A Routes
B Routes
C Routes
 
   
  Alphanumeric Routes in Victoria follow a few general guidelines in regards to what number they will be allocated. These guidelines are straightforward, and are designed to organise routes into a particular region, but there are a few exceptions which fall into their own special categories. All declared roads (roads which are the resposibility VicRoads) outside the Melbourne metropolitan region are all allocated a route number, which is either signed or unsigned depending on the importance of the route to the network.

  Numbering Regions
The numbers of SRNS is divided into 7 key areas:
 
     
   



Not to Scale - Rough guide only

 

Zone 1 - Routes X110 to X199
Covers the South Western Region of Victoria.

Zone 2 - Routes X200 to X299
Covers the Western and North Western Regions of Victoria, from Ballarat to Mildura.

Zone 3 - Routes X300 to X399
Covers Northern Victoria including Woodend, Bendigo, Shepparton, Yarrawonga, Yea and Mansfield.

Zone 4 - Routes X401 to X499
Covers the outer south eastern region of the Melbourne Metropolitan area, South and West Gippsland. Includes Belgrave, Wonthaggi and Sale.

Zone 5 - Routes X500 to X599
Covers the outer north eastern section of the Melbourne Metropolitan area and North Eastern Region. Includes Healesville, Bright and Corryong.

Zone 6 - Routes X600 to X699
Covers East Gippsland. From Bairnsdale to Genoa.

Zone 7 - Routes X700 to X799
Covers outer areas of Metropolitan Melbourne and North Central Victoria.

  Loop Route Numbering Rule  
     
  C Route numbers include the use of loop roads off M & A routes, whereby the first two digits relate to the M or A route number, and the third digit indicates the sequence of loop road, eg. C313 (Old Hume Highway / Euroa Main Road through Euroa) is the third loop road off the M31. Loop road numbers increase with travel away from Melbourne. [1]

NOTE: Routes which have a route number under the Loop Route Numbering Rule are not necessarily former alignments of the nearby M / A route. They are just routes which start and end at (or very near to) the same M / A route.

During March 2007, with the opening of the Albury Bypass, B400 was the latest B route to receive a loop route - B401. B401 (now B410) traverses the Bandiana Link Road in Wodonga.

Selected routes with Loop Routes:
 
 
Parent Route Loop Routes Notes
M1 / A1 C101 - C107, C109
A10
A10 proposed to replace the current 2007 route of M1 through Geelong [2].
M8 / A8 C801 - C805 Possible more loop routes if bypasses of town centres (eg. Ararat, Horsham) are built.
M31 C311 - C315 Unlikely for any more loop routes.
M39 / A39 C391 Possible more loop routes if bypasses of town centres (eg. Nagambie, Shepparton) are built. C391 replaced Alternative National Route 39.
M79 / A79 C791 - C794
A790
Possible more loop routes if bypasses of town centres (eg. Marlsbury, Elphinstone) are built.
B400 B410 Loop number for Bandiana Link Rd (originally B401 until October / November 2007).

  Other Numbering Principles    
     
 
  • Route numbers increase in a clockwise direction from western Victoria [1], much like the previous State Route Numbering System (blue-shields).
    .
  • M, A & B Routes which are continuous across State borders will retain their existing national route number [1]. Most of these routes were former National Routes (NR), and current National Highways ():
 
 
  SRNS Former number Route
  M1 - A1 National Route 1 Princes Freeway/Highway (East & West), Monash Freeway, West Gate Freeway, Citylink Southern Link
  M8 - A8 National Highway 8 Western Freeway / Highway
  B12 National Route 12 Mallee Highway
  A20 National Highway 20 Sturt Highway
  B23 National Route 23 Monaro Highway
  M31 National Highway 31 Hume Highway / Freeway
  M39 - A39 National Highway 39 Goulburn Valley Freeway / Highway
  B75 National Route 75 Northern Highway
  M79 - A79 National Route 79 Calder Freeway / Highway
 
     
 
  • Route numbers for A & B routes not continuous across State borders are readily distinguishable, ending in a zero. [1]
    .
  • Principal tourist routes have prominent numbers, ending in two zeros [1]. This is the reason why B400 Murray Valley Hwy is seemingly out of place from the numbering regions. These routes are identifiable with brown road name panel on reassurance directional signs (distance signs):
 
 
  B100 Great Ocean Road
  B400 Murray Valley Highway
  B500 Great Alpine Road
 
     
 
  • Route numbers are as continuous as possible connecting logical destination points [1].
    .
  • Roads which are not classified as declared roads, ie unclassified roads, but are connected between declared roads, can be given a C route if the full route has a valid tourist or connector function.[1]

  Unsigned Routes

Some declared roads are short (less than 5 km), and are only used for limited access. Routes such as these may not be provided with direction signs [1]. This guideline is in existence as all declared roads in regional Victoria has a route number. The majority of unsigned routes reside in provincial centres and associated urban areas, whereby the road name is more relevant, thus a number would provide little benefit for navigation. In Metropolitan Melbourne, most metropolitan freeways have been allocated an M route number, but only routes M1, M3 and M80 have been signed thus far.

  Route Classifications  
     
  M Routes   
     
 
'M' roads provide a consistent high standard of driving conditions, with divided carriageways, four traffic lanes, sealed shoulders and line marking that is easily visible in all weather conditions. 'M' roads are the primary road links connecting Melbourne and other capital cities and major provincial centres[3]. Contrary to popular belief, 'M' does not stand for Motorway, it is only a letter prefix.

  A Routes
 
   
 
'A' roads provide a similar high standard of driving conditions on a single carriageway. 'A' roads serve the same purpose as 'M' roads, but carry less traffic. [3]

  B Routes  
     
 
'B' roads are sealed roads, wide enough for two traffic lines, with good centre line and edge line marking, shoulders, and a high standard of guidepost delineation. 'B' roads provide the primary link for major regions not served by 'A' roads and for highly significant tourism regions. [3]

  C Routes
 
   
 
'C' roads are generally two lane sealed roads with shoulders. 'C' roads provide important links between population centres and between these centres and the primary transport network. [3]
