Looking at the letters on the stone, CHD means Connecticut Highway Department, now known as the Department of Transportation. This stone is the type that DOT installed when they built highways. Probably when route 15 was built.

Not exactly certin this is the mark, but it was the only stone found in the area and discription is inadaquit.
