> 1) Construction-wise the street should be considered to be a trunk-road (as it has exits and driveways, no at-grade intersections with other roads, etc.). IMHO primary seems to be ok, too.
> 2) Importance level: The road has - of course - local importance (classification: tertiary). The regional importance is also huge (classification: secondary). But the bypass is also connecting the SS12 which ends in the southern part of the city and re-beginns in the north (classification: primary).

I would classify it as primary, too. In Viareggio , where I live,
there is a similar road, that is "Variante Aurelia". It bypasses the
centre and connects SS1 Aurelia from South to North, even if in
Viareggio we have a "Via Aurelia" that cuts in the middle of the city.
Variante Aurelia has no at-grade intersections, two lanes per direction
and separate tracks, as in your case. It would be preferrable for
routing programs as well.
The only difference, I think, is that in your case it is a "comunal
road", wheras in my case the signs on the Variante are SS1 on blue
background, and these signs also indicate kilometers from Rome, just if
it was the SS1 Aurelia indeed.
Be sure to see how the signs are placed along that road, but by the way,
even if they don't indicate explicitly SS12 (and road signs have a white
- comunal - background), I would map the road as primary, given its
importance and physical characteristics.
