Brisbane is one of two Australian cities to have a Metroad route marking system (the other was Sydney). Introduced to Brisbane in 1995, the initial system consisted of routes 1-5 but a sixth was added following the opening of the Gateway Motorway extension (Southern Brisbane Bypass) in 1998.

Metroads form the priority routes into and through the metropolitan area. However with the implementation of alphanumeric routes in 2000 some Metroads have been replaced with alphanumeric designations.

September 2000: Metroad 1 was decommissioned in favour of M1, which covers the Pacific Motorway from Tugun to Eight Mile Plains and also the Gateway Motorway from Eight Mile Plains to Bald Hills.

2005: M1 was extended to take in the Bruce Highway from Bald Hills to Cooroy.

October 2006: Metroad 5 along Western Freeway between Darra and Toowong was replaced with M5. ¹
