As state leaders ponder suspending fuel taxes, officials at the Iowa Department of Transportation are also considering how they’d be effected. If the tax were not collected for 60 days, as one plan goes, between 65- and 80-million dollars would not be collected for road work.Iowa D-O-T spokeswoman Dena Gray-Fisher says the road construction and road-building work that’s now underway would -hopefully- move forward, even if there is a temporary interruption in the cash flow.State gas taxes account for about 20-cents on every gallon of gas. Gray-Fisher would not speculate on whether the suspension of the gas tax would mean hundreds, perhaps thousands, of people being put out of work.Some 14-thousand people are working on Iowa highway projects in one capacity or another. Gray-Fisher says even though gas prices have bounded from a dollar-seven to a dollar-77, the tax the state collects on gasoline hasn’t budged since 1989.
