Premier Lara Giddings and Infrastructure Minister David O'Byrne made the commitment to fund a second round of the community roads program yesterday.

"To keep modernising and diversifying our economy, we need high-quality and well maintained roads connecting each and every community," Ms Giddings said.

More than half of the funding will go to roads in the North and North-West, including three separate projects on Esk Main Road.

The most costly project is stage 2 of the duplication of Rokeby Main Road in the state's south at $15 million.

The promise includes $28 million in new money over the forward estimates.

Labor is yet to announce any savings measures to pay for its election promises despite Treasury predicting big deficits for the next four years.

The announcement prompted more complaints from rebel Labor backbencher Brenton Best.

The Braddon MHA criticised fellow Labor Braddon MHA Bryan Green for failing to secure more than the $1.2 million of the package for Mount Street in Burnie.

"I am pleased to see movement on getting Mount Street upgraded but appears Bryan Green doesn't really get it," Mr Best said. "It's not just the fact that the pavement is totally breaking up, there are embankment issues, realignments required, major undulations along the entire length."

Mr Best said he was also angry to see his name on a media release announcing the "inadequate" funding he had not approved.

Ms Giddings refused to criticise Mr Best, who has repeatedly lashed out at her and other Labor MPs.

"He's part of the Labor Party until he chooses not to be if he doesn't want to be.

"The people of Braddon will be able to decide who they want to represent them at the next election."

Deputy Liberal leader Jeremy Rockliff said Ms Giddings was weak to let Mr Best continue to get away with his blatant undisciplined behaviour.
