The name is incorrect for this road.  It needs to be split into two parts at the dog leg bend.  The part coming off Addison Road is actually called Gordon Lane, while the section at the bottom, after the dog leg, is Gordon Square.  I know how to change street names but not how to split an existing street into two.

I have a photo of the street sign at the top (junction with Addison Road) that demonstrates the correct names but I don't know how to upload that to this note.
