The Australian Government said it will invest a further A$4.2bn ($3.75bn) under its road-building programme for 2011-2012.

The funding will be added to the A$11.8bn ($10.55bn) investment for upgrading Australia’s national network, which will now total A$27.7bn ($24.7bn).

Upgrade work includes projects on the Pacific, Bruce and Hume highways and feeder roads, according to supplychainreview.com.au.

Other projects benefiting from the fund include improvement works on the Hunter Expressway, building the Kempsey bypass and investing in the Sapphire to Woolgoolga route in New South Wales and realigning the Cardwell Range in North Queensland.

Most of the projects are scheduled for completion by 2013.
