I think there might still be a hotel here, even though its entire building seems to have been deleted from OSM. Its name may have changed though: https://cambridgehotel.co.uk/

Gate here to footpath leading south. Footpath runs along field boundary and joins up with the (marked) footpath leading to Bin Brook.

Section of road opposite the Deakin Centre is now known as "Richard Howe Way" http://www.cuh.org.uk/cms/sites/default/files/misc/122284_July2013_270613_site_WEB.pdf

Is access down here public or private? I thought that it was private (based on walking past the end of the road the other week) but now it appears that there's a footpath leading from the west end of it. Is there actually public access to that?

It would be great if this were searchable as "JJ Thomson Avenue", with no space between the "J"s -- took me a moment to find it. Maybe even "J.J. Thomson", for the truly pedantic.

What is this blue line? Does it run into Bin Brook?

There seems to be a footpath route from the Coton Path (where there is a gate) to the path marked just south of this comment point. I went from the Bin Brook diversion channel on Barton Road to the Coton Path. It is a good route if you are on foot (not for bikes, or fragile shoes).

Is this the one sometimes called the Marine/Wolfson Building? If so, could it be entered as a alternate name so as to be searchable, please?
