JANESVILLE, Wis. (AP) — Gov. Scott Walker is looking for new ways to fund a state transportation budget that is projected to fall short by as much as $700 million by 2017. Walker was in Rock County on Tuesday for a Wisconsin Economic Development Corp. board meeting. The Republican governor says a project to widen Interstate 90 from the Illinois border to Madison is still a priority despite the projected shortfall. But Department of Transportation Secretary Mark Gottlieb says it is possible the $950 million project could be delayed if funding isn't found soon. Walker called the current method of relying on gas taxes for revenue unsustainable because cars are becoming more fuel efficient. He says his administration is looking at tax reforms to fund the department going forward.
