Some routes seem to have long (=relevant) access roads indicated with E numbering on OSM
However, I couldn't find any E number sign on GSV for the access roads nor any route in the HB...
E1:
It seems to be extended to the north, see OSM/GM
Exit 122 --> 228 according to OSM
New exit 122 missing
I could generally not find exit numbers for the northern segment on OSM/GM/GSV. What's your source?
E2:
Hard to find exit numbers on GSV but OSM confirms some of them and it seems to be fine
E3:
Indicated E6 on OSM and extended to the west (I've seen motorway signs on GSV)
E4:
Indicated E3 on GM/OSM
AguBlvd is exit 13 on OSM
E5:
Northern segments are indicated E4 on GM/OSM
JoseAbadSanAve --> JoseSanAve
E6:
Seems to be fine
