Z32 in the west of Zaragoza is actually signed as A68:
https://maps.app.goo.gl/wPMGCVSPnpWno6ov9 no signs further inbound though if I didn't miss any sign on GSV nor my travel today in both directions. OSM+GM do also indicate that numbering. We do have it on concurrency to A2 and A23 around Zaragoza. OSM also indicates A68 heading downtown in the east. I didn't find A68 signs on GSV and don't recall that I saw any when I drove it today.
