General Information:

The M15 segment of the Cunningham Highway is a full motorway standard route, that bypasses the Ipswich urban area. The route has its origins as a Super-2 expressway, but now features dual carriageways and 2 lanes in each direction.

The Cunningham Highway is named after the explorer and botanist Allan Cunningham. The Cunningham Highway forms an important link in South-East Queensland, and links Ipswich & Brisbane with the southern Darling Downs and forms part of the inland Brisbane-Sydney road route.

History:

• 1978: Construction commenced on the current alignment of Cunningham Hwy between Dinmore and Ripley. 2
• 7 December 1984: The Cunningham Hwy project between Dinmore and Ripley was opened by premier Sir Joh Bjelke Petersen. It was four lanes for most of its length. 2
• November 1995: The Ripley road interchange was completed. 2
• 23 December 1997: Woek performed at the Warrego Highway underpass to lower the road due to the 1958 bridge being quite low. 2
• April 2011: Correspondence from the Department of Transport and Main Roads refers to the section of Cunningham Hwy between Dinmore and Blackstone as numbered as M15. 3
• 2012: Signage upgrades show M15 as the route number between Dinmore and Blackstone.
