Thanks. There are three travelers. I've
added the alt labels, and also renamed O6 -> O7 and End -> Oda as there is a road connection at north end.
Let the north end in, despite the route is not yet finished, but I think it will be opened fast, and then we don't need to change it again.
The road was finished in 2018 (or earlier?) as you can see on GSV but is still
closed. I don't know why the motorway is closed,
wikipedia does not indicate the segment being opened nor mention it. It's likely in combination with the extension of the airport which is on hold though. See
my recent question on SSC. I don't expect it being opened anytime soon! However, it's illegally
accessable. I'd still prefer truncating but it's fine to me if you think different.
Please mark the topic solved if you still want to keep north end as-is.
