Totalling $644,000, the funds will originate in part from the council, and will be matched by the government under its budgeted Bridges Renewal Program.

It will be used to repair the Mona Vale Road bridge at Ladysmith and the Palmers Road bridge near Kyeamba.

"These decades old timber bridges are way past their used by date, and of course they have heavy farm implements go across them," said deputy prime minister and Riverina MP Michael McCormack.

"Their traffic is fairly regular, and in desperate need of being replaced."

It is understood the timber will be replaced with concrete for better durability, with works expected to be completed in two years.

It follows the investment in the upgrades of Eunony Bridge, which will total $10.6 million of combined state, federal and council funds.

"That will increase the weight limit on that bridge from current B-double standard to high, heavy B-double standard," said Wagga mayor Greg Conkey.

"That will open up heavy duty B-doubles to be able to access our Bomen Industrial Park."

During the Thursday announcement, questions arose over the status of the Gobbagombalin Bridge duplication project.

"The stats that we've heard on the Gobba Bridge is that there is about 8000 vehicle movements on that bridge per day," said mayor Conkey.

"With Estella and the suburbs to the north growing, we will need to duplicate that bridge at some stage, but not in the near future.

"When the need arises we will no doubt be lobbying for funding from both the state and federal governments, but at this stage, the people in the know tell us that the vehicle movements do not warrant at this stage."

However, Mr McCormack made a point of distancing the current federal government from the project.

"I do remember when that bridge was opened, I was the editor of The Daily Advertiser at the time, and I think Greg was the editor of The Leader at the time, and I do remember that was very much a state government project," he said.

"The fact is it was a state government project, and it's a state government road."

But, Mr McCormack did confirm that the federal government could "look at these sorts of things as time progresses".

Ahead of the long weekend, the federal government has also announced an $8 million upgrade to the nation's Driver Reviver stations.

"I know that the SES and other volunteers will be out this weekend staffing those Driver Reviver stations, and I urge and encourage people if they are on the road, take a break every two hours, make sure they pull in, have a cup of coffee and a break with those friendly SES workers and say 'thanks' to them," said Mr McCormack.
