Drove it this last week, intersection with I-25 is confusing, road from trinidad to stonewall is fairly level with some 60+mph streches, a number of Semis on the road. North of stonewall the road winds some with some steep grades to Cuchara Pass but I did see a couple of motorhomes on it. Shoulders on the road are nonexistent. North of the town of Cuchara the road levels out again but does wind some. At the intersection of 12 and 160, 160 does not have a stop sign so you do wait to make the turn.
