A20 through OCC has some long spurs which we don't draft for HB. However, there are two spurs with interchanges:
The one to exit 58 is (partially) signed as
D820E:
D820 http://www.openstreetmap.org/?lat=44.344737&lon=1.473713
D19/D149 http://www.openstreetmap.org/?lat=44.343609&lon=1.482028
A20 http://www.openstreetmap.org/?lat=44.342577&lon=1.500060
But the one to exit 57 is only indicated as
A20:
D49/D820 http://www.openstreetmap.org/?lat=44.547542&lon=1.479496
D22 http://www.openstreetmap.org/?lat=44.538403&lon=1.491306
A20 http://www.openstreetmap.org/?lat=44.530550&lon=1.512557
Both are grade-separated two-lane roads. It reminds me of
A641 with two interchanges - but it has its own number.
I'd add the first spur as D820E-46 (Lot departement) up to A20 but
I don't know how to deal with the second one. I think it is worth for adding to HB due to the interchange. Should I add it to eursf system?Thoughts?
