Hmmm... no responses... Well, even though I live in the area I haven't driven this road for 25 years, so my recollection is WAY out of date and a kinda hazy. But I'd be pretty sure you'd be OK as you would be on any NH secondary road. Maybe a bit bumpy, as the roads almost all are. The alternative would be to hop on 93 South, go 40 miles to 89 North, and head west to Claremont by way of Newport.
