We have been through that I-40 construction about 6 times in the last few months. We got stuck once, and sat for a long time.
It shuts down traffic from two lanes each direction, to one lane each way. As long as traffic is not heavy, and no one has a wreck, it doesn't slow you down as much as alternate routes do.
Our usual procedure is to watch Google Maps as we approach Santa Rosa from the east, or Clines Corners from the west. If it's short areas of "orange" in the construction zone, we stay on I-40. If there's a lot of red, we consider going around.
If you are at Santa Rosa and plan to go to Santa Fe, I'd take 84 toward Las Vegas, anyway. A bit further, but prettier drive. And if you've never been to Fort Union, Las Vegas, NM, Glorieta Pass battlefield, Pecos Monument, or Pecos Wilderness, those are off of I-25 as well.
