There is a need to preserve transport corridors to ensure that cost-effective transport infrastructure can be provided  in the future. Preserving transport corridors is a multi-step process that includes defining the corridor, applying land use controls, and acquiring the land required for the corridor.

The Victorian Government has undertaken planning for the Outer Metropolitan Ring Road and E6 corridor, and defined the corridor through application of a Public Acquisition Overlay in 2010. This allows for compulsory acquisition of property when required. It also gives VicRoads rights to request refusal of development applications.

The early protection and staged purchase of land in the corridor is aligned with Infrastructure Australia’s previous recommendations to the Council of Australian Governments, and consistent  with the 2016 Australian Infrastructure Plan.

Modelling by Infrastructure Australia in 2017 estimates the net cost of protecting and acquiring the Outer Metropolitan Ring Road/E6 and site for the proposed Western Interstate Freight Terminal at $2.3 billion (2016 prices) using a 7% real discount rate.


The proposal is for corridor preservation for the Outer Metropolitan Ring Road and E6 in Melbourne. The corridor has provision for a freeway (four to six lanes in each direction) and four rail tracks.  

The land required for the corridor was defined and preserved in 2010 through a Public Acquisition Overlay. The next step in preserving the corridor is acquisition of land in the corridor as it becomes available.
