General Information:

The New England and Cunningham Highways link South East Queensland to southern freight markets including Sydney, and is a major freight route to and from regional communities in northwest New South Wales and southwest Queensland. The National Highway 15 segments of the Cunningham Highway and New England Highway form part of the National Land Transport Network system for which the Commonwealth Government has full funding responsibility. 2

The route features a mix of rural highway standards (southwest of Ipswich to NSW border) and freeway standards (through the eastern suburbs of Ipswich).

As of 2022, the conversion from the National Highway 15 route number to M15 / A15 route number is a work in progress, with a mix of both numbers along the route.

Multiplexes along the route include:
National Route 42, for 14 km, between Warwick and Glengallon
