I believe there are two separate issues here:

1. I don't think your software should throw an error for 'destination' as the station is, after all, the bus's destination.

2. I don't think destination is appropriate on these ways as there's no signs (AFAIK) indicating restricted access to the station & car parks. There should be (& is) a destination tag for the stretch of road behind the multi-storey where there is a 'no through road' sign

What tag was preventing PSVs from using these roads?

Hi Welcome to OSM.
FYI
Most buildings are orthogonal in shape. In the iD editor there's a shortcut key to quantize (Q).
Road ways represent the centre line of the road so buildings should always be set back to allow for its width.
Tall buildings suffer from the 'parallax error' where it looks like they're leaning over. Always position a building to its base not its roof

Hi Steve
If the ways you're adding a Public Rights of ways, could you also add the relevant tags here please:
osm.wiki/Access_provisions_in_the_United_Kingdom

'Surface' is also a v. useful addition

Cheers

No it's not .
Please only make edits for which you have evidence. Guessing doesn't improve database quality.

What folly? There's nothing there. See the photo

Hi
What is 'Sham Bridge'?

in which case the construction=residential tag can be removed. As can the streets, presumably?

There's a chamfer & some steps were alongside:
osm.org/#map=19/51.45436/-2.58977

I would go with 'ground truth' where what can be seen on the ground takes priority and revert these edits:
osm.wiki/Ground_truth

What do the signs say?

Thanks for that. Now corrected. More likely PICNIC error.

You've previously added tags successfully. I believe you're more than capable of doing it yourself.

Hi
What's a 'religious_precinct'
osm.org/history#map=18/51.35309/-0.16693

Pleased be aware of building Polygons which already have tags. In this instance there are now two toilet onbjects.:

30th Aug? So the buses don't have access then?
Re: Closures. - it de[ends. I map what I see. That it was fully fenced off suggest it was major works.
In Combe Down no one appears to know what's going on. It's a site in transition moving down the road.

I didn't add the "chunky" roads. It's not something I see as relevant or important atm.

When I went in July it was being dug up & surrounded by Heras fencing. it looked like a major job. Has it been completed? Have you checked with First?.

Hi
Please use any validator with great caution. Best to amend only if you have local, on-ground knowledge.

From aerial imagery this path is clearly separated form the service road by a wall given the shadow cast. Knowing the steepness of the topography I suspect it's a retaining wall. They do not join.

leisure=recreation_ground is a valid tag
