ME US 201 Realignment
The only change here is deleting the ME104 point (and adding a new point at the north end of the realignment as ME11_S). Overlapping routes also need to be fixed. GSV already shows the realignment; ME100 obviously moves with US201, while it seems that ME11 and ME104 don't change except for point labels.
Well. MDOT didn't ask AASHTO for
201A now did they?
I don't see any other signage for it. The latest
MaineDOT_Public_Roads-shp shapefiles show that part of Main St as an inventory route, not any flavor of US201.
It's possible more signage has been installed or changed since the Google car went thru a couplefew months ago, and I may take a road trip up there next week to see what I can see.
Unless I see a compelling reason to do otherwise, I'm going to treat this as a one-off signfart and not a legitimate route.
