In Auckland Grafton Bridge is a buses, bicycle and pedestrian road, no cars allowed. Is there any way to add this restriction using Potlatch 2 to OpenStreetmap.

Also at the top of Khyber Pass Road in Auckland traffic going north on Symonds Streetis not allowed to turn right into Khyber Pass Road. How can I alter the map to include this restriction please.

Thanks

In New Lynn the street Astley Avenue now ends in a dead end , this was done when the traffic lights replaced the roundabout at Totara Ave, Wolverton Street and Portage Road.
I have tried to use the editor, but am not sure of how to do this and do not want to damage the map data. Can anyone let me know the process to make a road a dead end rather than a connecting road.

The same applies to a road in Newmarket that has been blocked to stop through traffic as it is parallel to a major route.

Thanks for any advise on how to do this
