THE Tinana interchange of the Bruce Hwy will receive $30.4 million to be upgraded in the 2014-15 Federal Budget.
Another $500 million of federal money will be spent on safety improvements and new overtaking lanes on the highway between the Wide Bay and Central Queensland, Wide Bay MP and Deputy MP Warren Truss said.
A further $3.75 million will go towards upgrading River Heads Rd and $1 million will be directed to Old Toogoom Rd.
The roads funding is among the gains for the Fraser Coast announced in the Federal Budget on Tuesday, which also included funding to go to sporting clubs and CCTV cameras across the region.
But the Fraser Coast is likely to feel the pain as well, with tough new measures introduced on the Disability Support Pension, family tax benefits and the Newstart allowance.
Hinkler and Wide Bay residents on the Family Tax Benefit B will now lose the benefit when their youngest child turns six.
The two electorates had more than 20,800 people on Family Tax Benefit B as of September last year.
The Federal Government also confirmed the eligibility age for an aged pension will rise to 70 by 2035.
Changes to the Disability Support Pension mean anyone under the age of 35 who is assessed to be able to work eight or more hours per week will be required to have a "participation plan" that focuses on getting work.
Unspecified sanctions for those who don't comply will be introduced.
The latest figures show Hinkler and Wide Bay have more than 17,800 residents on the disability pension.
Mr Truss said the budget would set the nation on a sustainable path.
"This Budget is an important part of the Coalition's Economic Action Strategy, which is designed to strengthen the economy, take pressure off families, and provide opportunities for business to create jobs," he said in a statement.
Both Mr Truss and Hinkler MP Keith Pitt said the changes in the budget were necessary.
