The state-owned Queensland Investment Corporation (QIC) is looking to sell off its multi-billion-dollar toll road division, Queensland Motorways.

A QIC spokesman has confirmed talks are underway concerning a possible auction of Queensland Motorways.

It owns tolling rights on the Gateway and Logan motorways, the Go Between Bridge, Legacy Way, and Clem Jones Tunnel in Brisbane.

The former Labor Government transferred ownership of Queensland Motorways to the QIC in 2010.

Queensland Motorways is held by QIC on behalf of the State's Defined Benefit Fund, which funds the State's public service superannuation obligations.

A possible target date for the sale is the end of June.

Premier Campbell Newman says he would prefer if Queensland Motorways was not sold.

Mr Newman says QIC is independent of government.

"I would like to see these continue to be held ultimately by Queenslanders but QIC have got to make the best financial decisions," he said.

"They've got a duty to make sure that they pay pensions and superannuation entitlements to Government and former government employees."
