MADISON, Wis. (AP) — Federal aid for Wisconsin highways has dropped by 3.6 percent, nearly $28 million, over the five years ending in 2013. That’s according to data obtained by The Associated Press. It shows a declining money stream that is worsening the state’s woes in paying for road projects. Wisconsin’s loss wasn’t as large as some neighboring states. Minnesota saw a nearly 33 percent drop because of unique circumstances, Michigan an 8 percent decline and Illinois a 6.4 percent dip. But the drop doesn’t help Wisconsin lawmakers fighting over how to pay for road work as gas tax revenue dwindles. Governor Scott Walker’s budget proposal calls for borrowing $1.3 billion for transportation, but lawmakers from both parties have objected.
