The building way/260469359 seems to be mostly a duplicate here. Not everything within it is building. There are some smaller buildings within it as yet to be mapped, but most of the big ones have been already.

There's more development (large buildings) on iPort now. Probably still not open, but may be visible from the path that runs under the M18 (assuming that's still open).

There's some new build housing being built here. Needs survey

Does any of this railway remain?
Is any of the former Harworth Colliery left (I'm guessing "no")?

If not, it would make sense to remove what no longer exists of Harworth Colliery.

From memory this is some sort of village hall or something, but what exactly was the name?

If there is a separate footpath to the road here (and it's not clear from the imagery that there is) presumably it does actually join the road at one or both ends?

Is this really a separate footpath or actually part of the A449? Does it join Bungham Lane at the south end?
