From here north, the trunk/motorway status should be reconsidered.

This short stretch of trunk in a motorway is not ok; the essence of motorway is not that each meter of it lacks side businesses, but long stretches. So if it's disqualified as motorway, that should extend for several km. Here, I think there's one access road southbound, and one industrial facility northbound, and that's it.

So my current thinking is either that trunk should extend south quite far, perhaps all the way to the really-really-trunk part. Or these parts should be flipped to motorway as being 99% motorwayish. I expect that everybody just drives 70 and doesn't notice the side stuff.

should the freedom trail have a hiking route relation?

MBTA schedule now shows stops here. Needs survey, parking, detailing.

is this really separate from the kiosk, and really here?

Without having visited, it seems obvious that one can traverse the parking lot. However, routing indicates a lack of connection.

(Noticed while viewing OSM tiles on MAPC trails map.)

Imagery shows a track along parts of this track, but not all. And, Kolob Terrace Road has a new alignment (was done in 2016-10) that is not visible in bing today. So the old tracks are suspect, given the degree of construction in the area.
