SA and Canberra closer on road plan

The federal and South Australian governments have held talks aimed at overcoming disagreements on how to fully redevelop Adelaide's north-south road corridor.

The two governments had been at odds before the recent state election, with the Commonwealth wanting to start the project with an upgrade at Darlington in the city's south.

The state government maintained a section of the road further north should be the priority.

But a meeting on Thursday between federal Assistant Minister for Infrastructure Jamie Briggs and new SA Transport and Infrastructure Minister Stephen Mullighan appears to have closed the gap.

Mr Briggs said he was now more confident about the project.

"We want to get the north-south corridor upgraded in a decade," he said.

Mr Mullighan described Thursday's meeting as productive.

"We've made very clear what our priority is and they've made very clear what their priority is," he said.

"What we're working on is how we can deliver both projects."

Mr Mullighan said talks would continue.
