Cosigned all the way to I-93 in Littleton. Now, whether one believes the relatively recent signage
What I see in the latest GMSV is the same as I saw on my trip through in May 2008.
Cosigned all the way to I-93 in Littleton, yes; even
as far as
NH US302 NH18_N.
...And then the trail goes cold. Over
here,
no mention.
I'm not against extending NH10 per se; I'd just want to be sure that if we do, it's well-considered & well-founded, to a sensible point, and not something we'd end up walking back later on.
or the NH route log Eric referenced in that CHM thread, that is the question.
The roadgeek.org reference can be found on archive.org.Wikipedia's cite, ISTR was never, even then, something I was able to access or view, and I just included it in the CHM thread to say "Hey, here's the source of that info."
What's Wikipedia's cite now? The GRANIT shapefiles. Thus I can't really call their figure of 122.476 mi definitive -- NH10 may have higher mileage than that, which just won't be shown in the file due to US302's mileage being shown instead.
What
DO I see in the shapefiles? There's the STREET_ALI attribute, which stores route numbers carried by a particular segment of roadway.
• Main St is "NH 10,NH 18,US 302"
• US302 is "NH 10,NH 116,NH 18,US 302"
(with a little "NH 10,NH 142,US 302" thrown in, right where you'd expect) right up to the
NH18/116 split.
• "NH 10,US 302" right up to US3, ending there. Plain as day.
So it's pretty clear that at least in some capacity, NH10 officially goes to US3 in Twin Mountain / Carroll.
Damn that gaping lack of signage, though.

Annoyingly puts this somewhat into "unsigned routes" territory.
May the discussion continue...
