I have always taken 315 rather than the out of the way 59 through Tenaha. 315 is faster, even taking into account that at some point there were always trucks bogging things down until a passing opportunity. According to Google Maps just now, 6 miles shorter and 7 minutes faster than 59.
But more importantly, I wanted nothing to do with the infamously and long time corrupt Tenaha police. Google them, they have a long, sordid history of sometimes random, sometimes targeted abuse of the asset forfeiture laws, extortion, etc. Both racial targeting and for other reasons, going back decades. Supposedly ended with a court settlement, but I don't trust them. To be clear, I'm very pro-police, but not the corrupt bad apples. Will never spend a cent in that town.
