Types of roads

"M" roads

M1 West Gate Freeway
West Gate Freeway, Altona North
M80 Western Ring Road
Western Ring Road, Laverton North

These roads are duplicated (dual carriageway) roadways with at least two lanes in each direction. The majority of these roadways are built to freeway standard.

In rural areas, they provide high standard links between Melbourne, other capital cities and major regional centres. Within Melbourne, they are urban freeways or tollways.

  • M1 - Monash Freeway / CityLink
  • M1 - Princes Freeway / Highway
  • M1 - West Gate Freeway

  • M780 - Western Port Highway

The CityLink sections of the M1 and M2, plus the EastLink section of the M3 are toll roads.

Exit numbers

"M" roads in Melbourne are progressively having freeway exit numbers installed along them. This allows drivers unfamiliar with the area to easily identify exits rather than rely just on a road or suburb name. It also gives drivers a sense of how far to their required exit so they can plan lane changes well in advance.

Exit numbers increase sequentially as the distance from Melbourne's CBD increases. Exits are denoted by a number, except for those within about 15 kilometres of the city centre which have the number prefixed by the bearing of the exit in relation to the city, such as "E" for east or "W" for west.

Lane restrictions

Eastern Freeway truck lane ban
Eastern Freeway, Kew

Trucks exceeding 4.5 tonnes of gross vehicle mass are banned from the furthermost right lane on a number of Victoria's freeways which carry 3 or more lanes of traffic. Buses and emergency vehicles are exempt from this ban.

Signage installed above lanes and along the median strip identify areas where this restriction applies.

"A" roads

A8 Western Highway
Western Highway near Stawell
A1 Princes Highway
Princes Highway near Lake Tyers

These roads are generally single carriageway roadways. The majority of them have sealed shoulders and overtaking lanes in some sections.

"C" roads

C546 Murray River Road
Murray River Road near Granya
C241 Ararat Road
Ararat - St Arnaud Road, Navarre

These roads are generally single carriageway roadways. Almost all of them are sealed and their standard is determined by usage and terrain.

They function as important links between population centres and also provide access links to the primary road network.

Some "C" roads are former highway routes with freeway bypasses having relieved them of much of their original through traffic. A few of these former highway routes are high quality dual carriageway roads, such as the Princes Highway (C101) through Berwick and Pakenham.

There are hundreds of "C" roads throughout Victoria.

Melbourne metropolitan routes

Metropolitan route 40 Springvale Road
Springvale Road, Chelsea Heights

These roads are located within Melbourne's metropolitan area and generally define major transport routes to the city and through the suburbs.

These routes may vary in standard from single carriageway roads to multi-lane arterials and highways.
