Is there really a legal (signed) turn restriction here?

With josm, select the existing way and then revert selection and restore deleted objects. I can do it if you want or give it a go yourself.

Wellington Platform 3 is not disused in that it has tracks and a working departure board, not sure what services use it though.

JackW's addition of motor_vehicle=designated is certainly wrong and should be removed.

It is longer than a pedestrian island, and is probably one of the earliest modal filters in OSM having existed for 13 years. This deletion should be reverted to preserve history.
It can be adjusted to look better if necessary but has always been correct.

Hi
Just wondering why you have removed way/41603394 ?
The road is certainly divided at that point and this allows only buses to travel along here from North to South.

This edit is very wrong, there is no physical separation, therefore there should only be one way. As you have mapped this traffic would be unable to access the petrol station without going onto the A5223 roundabout, which is incorrect.

Hi
The website link doesn't work, are you sure it exists as all I can find is a facebook page.

Hi Hannah
Welcome to OSM and thank you for your edit.

One small problem, in order for a path to be used it needs to be connected to other ways. For some reason you have stopped short of the roads at either end.

If you need any help please feel to ask.

Cheers Phil

Again there is no legal turn restriction here.

This junction was correctly mapped before, what are you trying to achieve?

There are no separated ways crossing the junction as you have mapped it.

This edit needs to be reverted.

Cheers Phil

I have reverted this edit. There is no physical separation so mapping two ways is wrong and your change has broken pedestrian routing.

Cheers Phil

Again why?

There is no turn restriction here.

Cheers Phil

Whilst not 'normal', there is no legal restriction on U turns here.

Turn restrictions should reflect only legal restrictions.

Cheers Phil

Why? It was correct previously.

The physical separation does not cross Glenfield Road and there are not two sets of lights.

This edit should be reverted.

Cheers Phil

Hi, this edit is a little odd. Wondering why you have changed the Wikipedia language to ab?

Cheers Phil

Hi
If an object is closed it should not be tagged with the amenity tag as this will lead map users to it despite it being closed. Using tagging such as disused:amenity=toilet is the preferred method. Names should be actual names and should not be used for descriptions or for information such as closed. As this isn't America Restroom is a very unlikely name.

Its not reflected in my memory or mapillary either https://www.mapillary.com/app/?pKey=281711566996173

Can you cite any in the UK, or mainland Europe? I cannot recall ever seeing such a thing having driven on motorways in many European countries. IMHO it is certainly a quest that should not be enabled in the UK
