'A' roads provide a similar high standard [to M routes] of driving conditions on a single carriageway. 'A' roads serve the same purpose as 'M' roads, but carry less traffic. [1]

  A routes form the principal links between provincial centres not covered by M routes. The majority of A routes are single carriageway roads, having full delineation, sealed shoulders and overtaking opportunities.

Currently,
ten A Routes have been designated across the state. In the terms of network importance, A routes perform the same purpose as M routes, the only substantial difference is that of lower traffic volumes.

The highways listed below have an A route number based on its previous National Route/Highway number. This is the case as interstate routes retain their number for consistency across the border[2] (eg. Calder Freeway's NR79 became A79). There are five of these such routes:
 
     
 
SRNS Former number Route
A1 National Route 1 Princes Highway (East & West)
NHA8 National Highway 8 Western Freeway / Highway
NHA20 National Highway 20 Sturt Highway
NHA39 National Highway 39 Goulburn Valley Highway
A79 National Route 79 Calder Highway
 
     
  Other A routes serve the purpose of major intra-state though routes such as the A200 Henty Highway, A300 Midland Highway, A420 Bass Highway and A440 South Gippsland Highway.

The majority of A routes were signed in 1997, with the 'newest' A route being A440 in 2003. Initially, the South Gippsland Highway was B440, but with route upgrades such as the Loch Bypass and numerous realignments, the route was promoted. The next route planned for introduction is the A10 along the current alignment of the Princes Hi
ghway between Corio and Waurn Ponds. It will replace M1 which will be moved onto the Geelong Ring Road when it opens.[2]

A routes include the road's name on reassurance direction signs.
