in november 2005, the royal automobile association (raa) released its recommendations to the south australian government in regards to the road network. south road was found to be the poorest road in the state, registering a 2/10 on the raa's scale. the recommendations given included $6 billion of funds to upgrade the roads of south australia – with $1.5–2 billion to be spent on south road alone. the raa's plan for the road included a 6 km tunnel from port road all the way to the anzac highway underpass and over/underpasses at six other major intersections and two rail crossings.
