INDIANAPOLIS (AP) — House Republicans want to increase taxes and fees paid by motorists in order to fund infrastructure improvements across Indiana for years to come.

House Speaker Brian Bosma unveiled a plan Wednesday that would increase the cost of fuel at the pump by 10-cents-a-gallon. Vehicle owners would also have to pay an additional $15 a year registration fee. And the proposal would make it easier for local governments to impose a wheel tax.

Republicans say state-commissioned studies show additional money is needed to pay for infrastructure maintenance and improvement projects.

Their plan will raise less than half of the roughly $1 billion a year the state says it needs for infrastructure

Critics, including Democrats, say the plan would shift more tax burden to the poor and middle class.
