The talk of pumping more money into transportation infrastructure comes on the heels of a House vote to gradually allow Michigan's 19-cents-a-gallon gas tax to go as high as 32 ½ cents over time.
It would initially generate $450 million a year, mostly by diverting money from elsewhere in the budget.
But because per-gallon fuel taxes could rise by no more than perhaps a penny a year, there's concern it wouldn't be enough to keep roads from falling further into disrepair.
A Senate committee plans to consider the House legislation this week. The question is to what extent senators may go above the $450 million marker laid down across the Capitol.
