What's happening

View our latest video animation which outlines the scope of the first contract. This involves widening Tonkin Highway and upgrading intersections at Hale Road and Welshpool Road to improve traffic flow.

We are in the project development phase, which investigates and defines the project’s technical scope. This involves assessing the various options for both contracts, which includes the three Tonkin Highway intersections at Hale, Welshpool and Kelvin Roads.

A number of activities have been undertaken to confirm the project scope, including:

  • ongoing stakeholder consultation to identify and resolve various issues/constraints, including nearby landowners, community and environmental groups;
  • concept design, geotechnical and site investigations, traffic modelling and environmental assessments to inform environmental processes and approvals.
