This tunnel was supposed to four-lane the E78 across the Appennines, but from what I've heard only one tube was finished. The eastern end of both tunnels is easily visible, but the western end is nearly impossible to find. I think it may be just northeast of Cantone, but I can't be sure. Where is the west end of the tunnel?

The west end is less well visible: https://www.google.com/maps/@43.5594792,12.2847489,118m/data=!3m1!1e3

Italian Wikipedia has an article about it: https://it.wikipedia.org/wiki/Galleria_della_Guinza

Seeing as I cannot read Italian, what is the story and prognosis on this one?

Since the first tube is done, they could make that portion of the route a two-lane road until they can carve the second tunnel, but instead it remains abandoned. You finished one half of the easier route- why not use it?

An EU directive (DIRECTIVE 2004/54/EC) regulates that longer tunnels require an escape route. This may either be a stand-alone escape tube, or a second traffic tube. So a single tube tunnel with no escape tube is not allowed.

This was implemented after a couple of disastrous tunnel fires with high fatality counts in the Alps in the late 1990s and early 2000s.
