Barca, on the other hand, said he is "very pessimistic" anything will be done to positively address transportation funding, cautioning voters not to believe "Republican rhetoric."

The Democrat accused Walker of kicking "a bigger can down a longer road that has potholes in it."

The primary focus in addressing the funding shortfall should be on cutting costs, Vos said, but beyond that, there may need to be a consideration of revenue-increasing measures. However, he said, that doesn't necessarily mean increasing the gas tax is the most logical solution.

Walker has warned lawmakers that he will veto any changes made to the budget that would "add to the overall burden of the taxpayers of the state."

The plan released by Walker's administration would cut funding for state highway programs while providing more money for local roads and existing highways, delay some major projects and authorize $500 million in new bonding.

Walker has stressed that the plan focuses on safety and maintenance while keeping bonding "at a reasonable level" and not raising taxes or fees.

The proposal would cut $447.4 million from state highway programs while offering an additional $69.7 million for maintenance and an additional $65 million for local roads.
