Iowa Governor Terry Branstad is planning to present legislators with a “whole series of options” to raise the amount of tax revenue available to repair and expand the state’s transportation network, but he won’t indicate which proposals he prefers.

In addition to a hike in the state’s per gallon tax on motor fuel, some of Branstad’s other ideas include raising the fees charged excessively heavy semi loads, collecting more taxes from the owners of electric and hybrid vehicles as well as charging the sales tax on fuel purchases. Branstad also suggests legislators might consider giving cities and counties authority to raise a local option sales tax, to finance local street and road projects.

Branstad says transportation infrastructure is “an important issue” for the state’s economy and the state is near a tipping point. Branstad is suggesting legislators should tackle the problem before spring, while gas prices as low.
