I will be driving to Angel Fire next week and just got a call from my friend who lives there. They have commenced major renovation of the 64 from the top of the pass down into AF... that is the good news and when it is complete the road will have been substantially widened making for an easier/safer trip.
The bad news is that it is now down to one lane led by a pilot car due to the massive amount of trees, boulders and debris they are having to remove and then comes new paving. Reportedly you can expect to sit for 20 to 30minutes traveling either direction.
You can skip the construction zone by going north through Taos and up to Questa and taking 38 east through Red River and then down to the 64 at Eagle Nest and on into AF. This will add about an hour but if you prefer to keep moving it is a gorgeous drive through the northern section of the "Enchanted Circle".
If you go through Red River consider a stop at Shotgun Willies for their smoked Brisket breakfast burrito smothered in warm Hatch green chili sauce. Looking forward to another visit next week. Also the Red River brewery is awesome and both are right on the main street on the south side -west end of town.
