Thanks, I've fixed it now. No idea what happened there

Hi is this still an A road? If it is then primary would be the correct tag. See here osm.wiki/Roads_in_the_United_Kingdom

Not sure why you added this since I already added the traffic light further back at the stop line

Hi, You seem to have removed the "to" from osm.org/relation/10104773. Just thought I'd let you know and I'll fix that for you. Also, just a small thing but it makes a difference; id allows you to change the roundabout to a perfect circle in the right-click menu. It just makes it look a bit neater

I've reversed the ways for you

Meant to say"all" instead of "any"

Also going to have to check but I don't think any of these are explicitly oneway so should probably not have oneway tags

Hi I think you forgot to reverse the ways at osm.org/way/1030697932 and osm.org/way/620134903. I cycle this path a lot and the direction is definitely opposite

height=0 and wall=noise_barrier also don't make sense on the wall. I understand this is the first edit though so I assume these were probably mistakes.

Hi, welcome to OSM. Is there a reason you have deleted the trees here? Also, I'd recommend reading this: osm.wiki/Good_changeset_comments.

No worries
