SA rail, roads net millions from the feds

South Australia has bagged $1.8 billion in road and rail funding in this year's federal budget.

A total of $1.4 billion has been set aside for North-South Road corridor projects.

That includes $177 million for upgrading the Pym Street to Regency Road stretch between Gawler and the River Torrens.

The government hopes it will increase freight movements and reduce travel time.

As expected, the state will receive $220 million for the electrification of the Gawler rail line.

"Current services on the Gawler rail line are reaching capacity and will be unable to support future demand," budget papers say.

The federal government has also allocated $160 million for the Joy Baluch bridge in Port Augusta.
