The Highway Trust Fund may become insolvent by 2015, according to the Congressional Budget Office. "The current trajectory of the Highway Trust Fund is unsustainable," CBO added. CBO said Congress could address the shortfall by raising the fuel tax by 10 cents per gallon or setting up another funding source. In any event, it appears that states will take on more of the burden of funding road projects, according to Robert Poole, director of transportation policy at the Reason Foundation. "Congress needs to give the states more tools to enable them to increase highway-user revenues and to shift more toward financing large-scale projects," Poole said.
