As complaints about Louisiana roads in quality and quantity have increased continually, if anything expect things to get worse on these accounts before they get better unless big changes are in the offing.
That implication came through in a recent discussion arranged by the Public Affairs Research Council, involving policy-makers and group representatives. They emphasized a recent Legislative Auditor report that noted the retail fuel excise tax will erode significantly in its ability to provide money for roads in order to tackle a $15 billion in expressed needs.
Two trends drive that: slow but steady improvement in overall gasoline efficiency and slow but steady growth in the proportion of non-fossil fuel engines on the road. Both reduce the amount of gas sold thus tax collected.
