My big pet peeve, besides the fact that Louisiana does a poor job of marking many of its routes (especially minor SRs), is that there is no distinction in signage between "primary" and "secondary" state highways. And yes, some Louisiana state highways are distinctly primary and others are distinctly secondary, though to be certain they aren't defined exactly that way in a legal sense anymore.
If you believed the signage, all state highways in La. are "primary." Big mistake. No way that, for example, LA 971 is of the same level of importance as, say, LA 67 or LA 10.
The new monochrome SR signage is ironic to me, because in the past I considered that perhaps a B&W state highway shield would be useful for signing the minor state routes, reserving the old green and white shields for primary routes only, thereby creating a needed distinction in signage.
Of course, my optimal solution would be to remove the vast majority of the minor routes from the state highway system altogether. But regrettably as I have come to learn over time, the mechanics of transportation politics in Louisiana are such that such a course of action would be complicated and essentially untenable. That's what happens when local "good old boy" types with their perpetual subsidy mentalities run the show, as they so often do here...
