Here is a link to old topo maps from 1928 and 1958 for comparison purposes. Look at the northwest corner.....and in the older map the northeast corner. The area near the old courthouse does seem changed. Looks like old Rt. 28 went through Courthouse Square and the new one bypasses it at Rt. 171 and then reconnects to 28.
Did you know that Rt. 28 starts in Orleans on Cape Cod and goes all the way to Ossipee?
