sangora suggests that the building mapped is really two buildings, one containing Safestore and one containing the trampoline park. See the comments on osm.org/changeset/55841556 for details.

The relationship between the path and the walls here looks wrong: I think the path runs alongside the wall, not crossing over it as currently mapped.

I suspect osm.org/way/703312977 and osm.org/node/297558232 are likely to be the same place of worship and need merging - this could do with a survey.

There's a footway mapped on a bridge here that doesn't exist. I'm fairly sure the bridge carries electricity cables over the canal to Amberley Road substation.

It's several years since I've been here, but there used to be a footpath between Bushy Close and Whaddon Way somewhere near here. I expect it's still there.

I believe the "steps" mapped here are really a waterway for excess water from the canal to flow down to the stream that runs south of New Bradwell Local Park towards the Great Ouse.
