Route marker signs

Route marker signs give you directions and information for the route you are:

  • approaching
  • travelling on
  • exiting from.

Route numbering

Route numbers identify roads as part of major routes connecting towns and cities. They are there to reassure you that you are continuing in the right direction for your journey.

Route numbers can appear as a stand-alone sign along the road or with a directional sign.

Route letters

A routes

An A route is a major arterial route in built-up areas that connects routes between cities and towns in rural areas.

B routes

B routes are alternative routes that connect cities and towns. They are normally a longer journey than an A route.

C routes

C route roads also connect road users to cities and towns, but they are not major routes like A or B routes.

M routes

An M route may replace an A route on freeways and motorways that extend out from the city.
