- Three days of closed-door meetings ended with lawmakers rolling out a plan to raise more than $1.2 billion for Michigan’s roads. Before that plan gets to the voters, lawmakers have to approve it. Lawmakers are finalizing the legislation, which then has to be voted on. The plan includes increasing the sales tax from 6 percent to 7 percent, which needs a two-thirds majority vote before it can go on the May ballot. The House and Senate didn't like each other's plans so the alternative plan of putting it to the voters is what won out.
