I would have expected Louisiana at the top of the list of states with inadequate state highways per capita because of its extremely dense state highway network (it has highway numbers going into four digits) and a huge number of bridges California has a very thin net of state highways for its population size. To be sure, many of those (including most or all of 22, 24, 54, 57, 60, 85, 87, and 91) are Interstate-quality freeways. That's before I mention long segments of 14, 58, 99, and [US] 101.
Michigan proves surprisingly good -- until one realizes how thin the network of state highways is.
But as is my habit, here is a map. "Red" is for a high per capita cost of repairing roads (as in "STOP", and "green" (as in "GO") is for low costs per capita with yellow (as in "CAUTION") in the middle. Shades darken toward the extremes and lighten in the middle.
