From Edna take 59 north to the FM 530 road exit (first exit after Love's) turn left under overpass and head north stay on 530 until you reach Halletesville. Simple. If coming from the north on 59 take the 530 exit turn right on 530 etc.
This route goes through south Texas farm/ranch land everything from Rice to wheat and livestock.
Road is an average farm to Market road for Texas. Nice long sweepers broken up with some straights. Traffic is bad during cutting and planting but most of the time smooth sailing!
Nothing much along the way but an old bar near the h'ville end both towns have nice places for grub.
