RICHMOND, Va.— Gov. Bob McDonnell plans to unveil his long-promised transportation funding reform package in Richmond less than a day before state lawmakers convene for their 2013 session.

McDonnell has scheduled a Tuesday afternoon news conference to outline what aides say is a sweeping package that was still a work in progress late last week.

The governor, entering the fourth and final year of the single, nonrenewable term Virginia uniquely allows its governors, has kept details of the program closely limited to a handful of top aides and advisers.

The only financial portion of the program he has discussed publicly would shift about $48 million from the General Fund by designating a sliver of the state sales tax for transportation use.
