O7 southwest of O3 is signed as O3 on km posts according to my filed check. We can also see it on
June 2022 GSV. Westbound direction signs are
green without road numbers. It's also signed as O3 on eastbound direction signs according to
June 2022 GSV - well, E80 too which
could mean To O3 and To E80
Nonetheless, I think that O7 needs to be truncated and a new O3 branch needs to be added because the connector is signed and has interchanges.
In addition, O7 exit numbering is off by 1 from exit 23 (24) to east end, see OSM, confirmed by
2020 GSV.
Exit 24 (which should be 25) is off. Should be on the main line.
