I believe that way 234840002 is too long. It has access=no tag. It should finish at the intersection with the way 234733985, I think.
Here’s the Strava heatmap for this area:
Am I right here? If so how to make this change using iD (in-browser editor)?
Probably you are right - this way is too long. You can divide this way on iD Editor:
- Select node (left mouse button) on intersection.
- Use right mouse button for context menu and choose scissors (shortcut ‘X’ key) - example on picture
- Change tags for shorter way part.
