Add up the salary's and yes. That and the country roads are wayyy over-designed. And the rock roads use too much limestone. Yes, its cheap but degrades quickly. Mix in a 5-10% rate of river rock and they would last much longer.
Our county engineer was obsessed with "crowning" the roads and thought that would get rid of all the problems. If he'd drive them more often he would know that its not the rain that is the problem. The problems really come when the frost comes out and they soften from the bottom up. So he spent at least $750,000 last year making a heck of a mess and they are pretty much the same now as two-years ago at this time. And he left his $100k salary to hire his buds that didn't know how to run a road grader.
