Thank you for the response and for your updates. I see there are some segments with no intersections, but there are still areas that do not quite fit the requirements for motorway. For example, there is a footway crossing at (https://www.openstreetmap.org/way/312991886), which is generally not allowed on motorways. If you feel like the areas by https://www.openstreetmap.org/way/937486005 and https://www.openstreetmap.org/way/956645341 should be motorway, how would you feel about adding no-u-turn restrictions to these ways?
