I would call them covered=yes (attribute)
or maybe covered=all_sides
yes, and how to tag a partly enclosed structure like a gallery in alpine
regions (usually covered on top and closed on one side by a heavy concrete
structure to protect the street from falling rock and snow).
so this could be covered=gallery
Even though gallery is somehow ambiguous if I recall right.
btw: those "cut and cover"-structures are indeed considered tunnels in some
building standards when they're logger than 80 metres (German Standard) or
~160 metres (american standard as of wikipedia:en). Should we ignore this
for simplicity or would it meet with what you usually expect by a tunnel?
