There are 3 sections to 'Wangi Road', with the southern section directly south, split by a train line and a large hill. The road doesn't connect. Directly to the north is also a section of Wangi Road, however, the middle section and the northern section are separated by a creek.

There is a dirt road here with 2 houses. The road is named Wangi Road and is the northernmost section of Wangi Road. The 3 sections are not connected but are simply named the same.

This edit is really dubious. There's nothing on RMS about a proposal, let alone a third Hexham crossing. Similarly about the M1-M2 link at the other end of this changeset, which has proposal documents, but no work started on RMS's website.

This intersection is now controlled by traffic lights. The roundabout is no longer there.
