I just spent quite a bit of time following roads on Google Maps and here’s what I found:
Gold Brook Rd goes off the north side of 27 past Eustis, and turns into Beaudry Rd after Spencer Bale Rd on the right (maybe what I thought was Spencer Rd?)
Beaudry Rd continues and turns BACK to Gold Brook Rd after Kibby Mtn Rd, passes West Branch, Haynestown, Pine Tree, and Appleton Rds, then the next road on the right is Holeb Rd.
Gold Brook continues on in a generally NW direction toward the border but stops about 5 miles from it.
Holeb Rd goes generally NE, passing Moose Rd and Barrett Rd on the right, and a little after Barrett Rd becomes Beaudry Rd again.
Beaudry Rd continues for a few miles and all of a sudden in the middle of nowhere becomes Old Skinner Rd.
This continues for a short distance, maybe a mile or so, before meeting Holeb Rd at a kind of upside-down T.
If you go left at the T (the vertical line) you'll eventually hit 201 and if you go straight (the horizontal line) you’ll reach Holeb Village after passing ANOTHER road on the right labeled as Old Skinner Rd. The last time I was at that T the sign said Beaudry Rd, not Old Skinner Rd. So that’s why I wouldn’t trust GPS or road names, you might be on the right road but when the roads start and stop at random and have 2 or 3 names…
I don’t think I’ve ever been much more than 5 or 6 miles down Beaudry Rd from the Holeb Rd/Beaudry Rd split, and that was over 4 years ago, so I can’t verify any of the road names and changes as they appear on the map. Google Maps used to show a Spencer Rd route to get to the Eustis area, but now it has you going down 201 to Solon, taking 201A until you hit Embden, then taking a couple town roads until you reach 16. Follow that through New Portland until you hit 27 at Kingfield.
