Hmmmm, let's think about this relo on the AT..
All these USGS maps were downloaded from this page. The first is Egremont, 1948 and a scale of 1:31680.
Appalachian Trail: Enters from Egremont at 12.5 m. and crosses Hubbard Brook on the Sheffield-South Egremont Rd. At 12.6 m. is the Shays' Rebellion Battlefield Site, indicated by a stone marker. Left from the Sheffield Rd. on a dirt road at 13.2 m. and R. on US 7 at 14.4 m. At 14.5 m. L. across the Housatonic River at Upper Bridge to East Rd., 15 m. Left on East Rd. to 15.4 m. where the Trail swings R. across fields and woods roads to a road running N.-S. between East and June Mts. Right on this road a short distance and then L. on the Soda Springs Rd. From this road the Trail ascends over a series of ledges and at about 17 m. enters Great Barrington.

Next we have the same titled map from 1958 and a scale of 1:24000.
And still a lot of road walking.
Now I add the map (same title) from 1973 and 1;24000 scale.
Recall, I was hiking this in 1975 and didn't have a guide book or map, so I was depending on the blazes for me to cross the valley. I did this on the road.
Surprisingly, in 1997, the new 25000 scale maps and now called Great Barrington, since they were printed on larger sheets of paper, the trail returned to the road?
Finally, the most recent map in 2021 shows the newest corridor of the trail on protected NPS lands.
