"I certainly think we need to improve our roads, but I'm not confident that we've managed the money that we have already invested in them very well. I'm also concerned about using a sales tax as the means for doing it."
Hanaway adds that the decision will ultimately be up to voters, but adds that the tax will impact Missouri residents far more than it would travelers also using the state's roads.
"The likelihood that people driving across I-70 or I-44 from out of state will be paying sales taxes is pretty minimal, but the people that live in Missouri will have to pay a lot more."
MoDOT says the increase is needed because they've been seeing a steady drop in income from the state's gasoline tax due to more people owning more fuel-efficient vehicles.
