The project aims to introduce intelligent transport systems and widen the M2 corridor from Melbourne airport through to the M1, along the Tullamarine Freeway and CityLink.  

In 2014, Infrastructure Australia recommended that the CityLink Tullamarine Widening Project move from ‘New Submission’ to ‘Threshold’ on the Infrastructure Priority List.

The proposed solution includes widening of the Tullamarine Freeway and CityLink (to the M1), by at least one additional lane in each direction; the implementation of a Motorway Management System; and various other works and upgrades.

In 2015, Infrastructure Australia recommended that the CityLink – Tullamarine Widening Project move from ‘Threshold’ to ‘Ready to Proceed’ on the Infrastructure Priority List.
