Michigan's lawmakers appear headed back to the drawing board for a fix for the state's moribund roads.

Voters on Tuesday rejected Proposal 1 by a wide margin. An unofficially final tally of ballots from the Secretary of State shows about 80 percent voting against the proposal.

The measure, which was vehemently supported by Gov. Rick Snyder and a bipartisan group of legislators, would have raised Michigan's sales tax from 6 percent to 7 percent. It also would have increased the Earned Income Tax Credit, created new and steeper taxes on wholesale fuel, done away with vehicle registration fee discounts and more.

Proposal 1 was projected to generate $1.25 billion in funding for work on Michigan's roads per year. It also was estimated to raise $600 million annually for schools, mass transit, municipalities and Michigan's general fund.

But the plan was met with loud opposition throughout the campaign as many Michigan voters voiced displeasure with state legislators' failure to come up with a solution to the crumbling infrastructure on their own. The most recent public opinion poll conducted on the proposal showed 61 percent in opposition.
