The US$644 million South Road upgrade in Adelaide will be 1km longer than planned following cost savings measures, according to a report by the Australian Broadcasting Corporation.
Much of the savings were gained through design improvements and fewer relocations of services such as gas, water and electricity.
A report by ABC in May said that completely turning Adelaide's South Road into a non-stop north-south corridor in the next decade 10 will cost just over $5.04 billion.
ABC News said it had seen a planning study costing $6 million, prepared by the South Australia state government, showing 10 road projects need to be completed.
That does not include two projects that have already been funded: the Darlington Road upgrade and River Torrens to Torrens Road upgrade.
The costs include building elevated and lowered sections of roadway, and acquiring land, homes and businesses, which will cost more than $1 billion alone.
