A proposal that would earmark some sales tax for transportation has been made in the state senate. Senator Jim Mathewson suggests increasing the sales tax by one cent and adding two cents to the fuel tax to raise $650 million dollars a year. It’s the first time general sales tax revenue would be applied to transportation. Governor Holden says any new transportation plan has to plug into a broader economic program. He won’t say if he will support Mathewson’s idea. Even Mathewson says he’s not sure of the proposal’s viability.
