Increases in travel demand and expected developments along parts of the Cunningham Highway are likely to create additional safety considerations and capacity constraints, particularly at the intersection with Ipswich–Rosewood Road.


The proposal investigated strategic upgrades to a 4.75-kilometre section of the Cunningham Highway between Warwick Road at Yamanto and Ebenezer Creek, to the south west of Ipswich.

The proposal examined the delivery of a highway interchange and new alignment connecting the Cunningham Highway, Centenary Motorway extension and the Western Ipswich Bypass.


The project is expected to:

  • deliver travel time cost savings
  • deliver vehicle operating cost savings
  • lower accident rates
  • enhance opportunity for major economic and defence-related development earmarked for the region.


Referred to Infrastructure Australia for consideration.
