According to the article, it's the section of Ermin Street between Hobley Drive/Highworth Road and Swindon Road that's affected. At the moment it's southbound only for buses, and if you zoom in on
Google maps you can see that from the road markings. The proposal is to make it two way for buses... like it used to be less than 10 years ago. Indeed, I recall one of the residents mentioned in the article saying, shortly after they moved into their house, how convenient it could be to have a bus stop outside their front door.
The school mentioned is Grange Infants School.
