It is not uncommon to experience pain in one part of the body when the root of the problem is elsewhere. For instance, arm soreness and weakness might actually be a symptom of something amiss in the shoulder or neck area. This misdirected pain is called “referred pain.” Since this article is about road funding; we'll use the word “detoured” instead.
At a glance it seems that the state doesn't collect enough funds from fuel taxes to adequately maintain roads and bridges. A closer look reveals something quite different. A lot of tax dollars collected at the pump are detoured and used for things other than roads. That's the real root of the problem.
