Only one shows up the rest are deleted

That overpass is is open https://www.halifaxtoday.ca/local-news/new-highway-102103-ramp-and-overpass-will-open-on-monday-update-1743298

Thanks for pointing it out - fixed

the one that shares boundaries with Saint John County

New Brunswick shares a border with the USa

Contiguous United States is suppose tb the lower 48 but this relation causes issues when trying to merge boundaries for the whole US and should have a level like AL 3

Revert for now

No but the history has shown it was fixed by another mapper

military areas are administrated areas

It was done from a way tagged railway

The way is part of a r
elation

I cleaned up the boundaries so Beaver Lake 17 + Beaver Dam share a way plus Beaver Lake 17 +Pleasant Valley share a way

I see what your saying I have to give it aa try

The inner relation is a first nations reserve which is not a part of HRM

the boundaries that where left behind match where they intersect on the interpolation lines on the roads the ones deleted where off while the newer one were exact

There are no cities in NS anymore since 1996 Shearwater is admin 8 community according to osm.wiki/Canada_admin_level
HRM is an upper tier municipalityAL 6 Shearwater is a division of HRM AL 8

this is the current boundary Stats Canada does not define boundaries in Nova Scotia the government of NS does

Duplicate Ways from older Stats Canada that were 50 meters off

Fixed it

something that is an exact copy of something else:
