I'm completing it over the next couple of days. Assuming you're talking about the part after granja de moreruela (edit: which you are!), there is quite a bit of road walking and some highway walking but i think it's more reflective of the higher population as you approach the North West. I didn't walk it previously so can't comment on works other than to say the authorities have the route well signposted, have paths away from roads as often as possible (even if just alongside the road) and plenty of water fountains.
One thing to note is that with the motorway in place, many of the roads you're walking on will be devoid of traffic and there's plenty of verges and laneways apart from road walking.
The weather after Easter was pretty wet and with a bad forecast and a 40km stage, i bet there would be few pilgrims on the Verín variant between a Gudiña and Ourense. Empty albergues. So i enjoyed a bit more solitude there!
Right now in the last 100km the albergues are full, and there's many clicky little groups of 4 or so people that are common on the last 100km (for better or worse).
PS Castro Dozon has no open albergue. Book accommodation in advance unless you want a long stage like my 30km today! Also ourense city had max temps of 32 degrees a few days ago, just days after max temps of single digits and rain at night that turned paths to mud.
To answer your question: is it beautiful? Yes. Was it the most beautiful part of my camino from Almería? - also no!
