A proposal to raise nearly $2 billion annually for the state’s roads, bridges and mass transit systems flopped recently in the legislature, partly because it would end up increasing prices at the pump through a wholesale fuel tax increase.

But state Representative Brad Roae, R-Crawford, said there’s a way to raise the funds without raising taxes. Roae said he plans to introduce legislation that would provide $6.6 billion for road and bridge repairs in its first decade by relying on sales tax revenue collected on automobile purchases in the state.
