THE West Gate Freeway's traffic management system will get a $12.5 million boost in the federal budget with the government promising there will be no cuts to Victorian infrastructure projects.

The budget will deliver a $901 million instalment for infrastructure to Victoria, part of a six-year nation-building scheme that began in 2008.

Infrastructure Minister Anthony Albanese also announced completion dates for some major projects.

"From the outset we were determined to return the budget to surplus without sacrificing the long-term investments vital to securing our future prosperity,'' he said.

''That's why the infrastructure budget has been maintained and no Victorian projects delayed or cancelled.''

The $12.5 million will help pay for the latest freeway management technology along the West Gate Freeway, which is used by 160,000 vehicles a day.

Mr Albanese said that by the end of June next year a 17-kilometre Nagambie bypass should be finished as well as construction of the next stage of the Geelong Ring Road.
