ITA: A11Via, or A11A12?

[yakra]

A11, A12, E76 & E80 all have a point labeled A11A12.
The route in the HB is A11Via, which OSM also has labeled as A11A12.
Which is right?

This one dates from the days of CHM. I'll try and remember how this came about. Presumably, A11Via was a change and the labels on the other routes weren't changed.

Having just left the A11 mainline, this sign makes no mention of A12 - the road is the A11, not A11A12. Except it's signed as A12 on the directional signage.

This is very clear - the A11 goes to Viareggio. There's no A11/A12 signs. It's A11 to the A12, and sometimes reference to the A11 bit is missing.

Renaming points, not the route.
