Since I've had no reply. I am reverting this change back to how it was.

Hi there, you changed the classification of the A39 between J23 M5 and Street.
This is very unexpected, may I ask you double check this change as I believe you may be misinformed in what the requirements for UK road tagging are.
Confusionaly, a tagged "trunk" road doesn't have to be a "trunk" road as classified by UK legislation, but rather have "primary route" status. This is easily checked by if the signs along its route (not signs pointing off the route) have a green background. If they do it is more than likely to be a primary route. Local councils can change primary route status, but not necessarily update road signs.
May I ask that this is reverted to trunk, and further ask the local council (normally via a FOI) whether the A39 stretch in question if primary or not.
If you would like me to change it back, just say and I'll be more than happy

I know that this is an old edit. But is there a reason why you made the entire development at Sandrocks residential.
I did a survey a couple of days ago and a 1/4 of it is still under construction.
I've updated it to reflect the current situation.

Is this the current layout of the A23 (and surrounding road), or is this what the outcome of the changes will be?

Please check what should be added to the map and the correct tags to use. I've removed the markings as they are not standard in aeroway=*?uselang=en-GB

Welcome to OSM MrJeeves, I see you have added some houses in Lindfield. Great job! However when adding buildings please ensure that they are square. You can do this by pressing "s" when you have the object selected in the ID editor.
Also if the houses on a street are all the same size and orientation, you can just copy and paste the object, that way it all looks neat.
Any questions, don't hesitate to ask.

Hi, you have seemed to of removed the oneway tag to the start of the Northbound carriageway

In the UK, roads with 'Primary Route' Status are given the 'Trunk' highway type. Primary routes are those with Green Signs with Yellow text and this sort section of the A259 has got it, other parts of the A259 have also got this delegation but not the entire route. Primary route A roads are normally dual carriageways (like the A24), but don't have to be (such as most of the A272). Non-Primary A roads (signs are white with black text) are given the 'Primary' Highway type.

Hope this clears this confusion up

That must of been a mistake.
Corrected

Since I got no reply i'm going to revert it back

Regarding you changing the A270 from Primary to Trunk link on near Falmer.
I'd say that it was correct before you changed it. Could you justify why you think it should be trunk_link and not primary or revert it.
Thanks,
Thomas

Currently adding C routes in West Sussex and noticed that this road is marked as Primary even though its not A road.
Following the guidelines i'm changing this to teritorial. I would agree that it should be more than that, maybe secondary but its not a B road.

Nice addition with the bunker. But is Military the best attribute?
Maybe something like memorial or museum is more appropriate due to it not being used for military purposes anymore?

True.

Really?
I know school is boring, but this change ain't helping anyone.

Thank you robert,
I have checked it again and i am certain that it is called brooklands

@BCNorwich I normally do, just sometimes when there is the occasional one or two adjacent houses it adds to the amount of effort.
How does one square builds up with each other? Im using the iD editor and it makes it a pain to line buildings up with each other.

Thanks for fixing this, this area has been bugging me for a while and after quite a bit of research I finally found out it is a spur of the A272, I come back to do it and someone already had!

Hi Maarssen Mapper.
Was not intentional and not quite sure how some of these things work. so if you would like to fix it.

Reverting back to secondary
