Metroad

Metroads were the primary road routes serving the Sydney and Brisbane metropolitan areas from the 1990s to the early 2010s.

The Metroads formed a network of radial and circumferential routes throughout the cities, simplifying navigation.

Metroads have been progressively phased out in both Sydney and Brisbane, replaced by alphanumeric route numbers.

As of 2015, the Department of Main Roads in Queensland have no plans to convert/decommission the remaining Metroad sections within Brisbane.

[1] All Metroads in Sydney were completely replaced in 2013 with equivalent alphanumeric road markers.

Most Metroads have since been completely or partially replaced with equivalent alphanumeric road markers.
