There is a sign here indicating that buses 223, 182 and 83 are diverted up Park Lane on event days. It was an event day, but that was not happening.

Need to:
1) find rule for when they are diverted (may be difficult);

2) trace routes when they are actually diverted;

3) establish whether there is a re-routing in the southbound direction, as well.

One of the blocks of flats around here is undergoing extensive renovation and is currently empty, but I'm not sure if it is one that is already mapped.

The building housing Citigen is the old Port of London Authority building, and still has that name clearly painted on it, which I think gives it some on the ground status, beyond its historical status.

Unfortunately Citigen's site isn't tagged as a building, so I don't know if what is mapped is equivalent to the building, and if not, the exact extent of the building, so I don't have enough information to map it myself.

Parts of the West side of Lacon House are now a construction site. Needs a more detailed survey to work out the boundary (basically the LA Fitness side is currently unaffected.)

When I went round this, yesterday, the stop were on the West side of the loop (which was anti-clockwise), That was at least the case for the 186.

There seems to be a big problem in this border area with using names not as names, but as tagging for the renderer, and also not actually setting the meta-data that should really be used for the information.

Please see: osm.wiki/Names#Name_is_the_name_only , osm.wiki/Tagging_for_the_renderer and the discussion at https://forum.openstreetmap.org/viewtopic.php?id=60390

For example, putting "(Buses)" in a road is usually wrong and will never stop routers from sending cars down that lane. Naming a causeway "Causeway" is also wrong. Either it has a full name, or it should not be named at all.
