I've never been sure either. Cyclists and pedestrians are prohibited across The Thames, but a cycle shuttle service can take cyclists across free of charge on request, hence the 'dismount'. Feel free to change, I didn't put that tag there initially, but have kept consistency on the route the cycle shuttle runs.

Please do not split ways like this. Ways should only be split where there are prolonged central barriers, not paint.

Please take care when adding tags, you have managed to tag a woodland and a boundary as 60 mph

Please do not do this. As per the wiki - "The slip roads/ramps are usually considered to "belong" to the through highway they exit and enter". This is predominantly the case classification- and operator-wise too in the UK

I changed the tags from maxheight to height which is more appropriate.

I was not aware of the differences, I assumed that the latter was more apt given the input box on iD

Hi, not sure if you added these tags, but please don't tag ways under bridges as tunnels. A crossing can't both be a bridge and a tunnel at the same time.

Are these official junction numbers?

Thanks, must have missed that

I'm sorry? I was being polite...

Hi, please change maxspeed:type tags when changing maxspeed tags. Thanks!

Hi, please remember to change maxspeed:type tags when changing maxspeed tags

You also appear to have missed several sections when changing the maxspeed tags. Please be more careful in future.

No evidence supporting this. Reverting.

Hey, a reminder that dual carriageways have a 70 mph national speed limit. I've amended the road near J18.

Thanks, a lot of learning constantly with this. The wiki has some info on the different maxspeed:type tags

There needs to be terminal signs to indicate a change of speed limit from national speed limit to 30 mph. In this case the national speed limit repeaters have just fallen off or been neglected over the years. I recommend asking National Highways if you want to know more, but without terminal signs I shall mark this as 60 as it was.

Hi, please make sure to change maxspeed:type tags when changing maxspeed tags. Cheers.
