[Talk-ca] Problem with overpasses in NB??

Provinces provide roads to NRCan that simply package it for GeoBase and
Canvec. I might be wrong but I am on the impression that some provinces (not
all) create vertices at intersections (2D) and do not consider the elevation
(3D). When converting to OSM, duplicated vertices (one on each road) are
merged in one node.

That might explain what you found
Same thing for double spaces in name

That does look like an error, I've fixed that one.  The history on the
involved objects is short, and suggests that it is an import.  Do you want
to contact the mapper and ask about the matter?
