A slightly different site, but I recall reading about a low raised earth bank described as a 'processional way' between Gibb Hill and Arbor Low.
Dunno if this would qualify as a low road, but I've read of similar 'tracks' between other sites. I'm sure there were many, now lost, routes of interconnectedness between related ritual and domestic sites.

You can see the earthwork between Arbor Low and Gibb Hill quite clearly on google earth/maps.
