 Hi,

 Something like this:

 I didn't find anything on the wiki or tagwatch. Maybe it's even
 questionable to have a special tag since it is either a normal
 extension of a pedestrian place or a normal sidewalk but under a
 building.
 Thanks for you advices.

IMHO it could be tagged as footway and for the particular construction
you could use a more specific tag (like: way_type or something
special).

Did you search for archway or for arcade and
http://en.wikipedia.org/wiki/Colonnade as well? The latter 2 are more
construction specific (I think, I am not English native though). Note
that arcades have arced ceiling/construction where colonnades have
ususally flat ones (the term concentrates on the columns where arcade
focuses on the arcs).

An arcade usually cuts through a block, rather than running alongside a
road. I'd have said colonnade was about right, though they're not exactly
common in the UK (the two level shops at Chester spring to mind, but they
are probably peculiar to themselves). We do have what can best be described
as concrete awnings, eg in Birmingham, but they are stricly functional,
and probably best described as something like covered=yes.

I'd probably go for footway=colonnade

Hello,

I don't think colonnade would fit what we need here. The arcades are
always closed on one side and in ancient Greece, the closed side had
shops in it, which is usually not the case with colonnades at all. The
example given is pretty good, and it is relatively common in some parts
of France. Orleans and Tours would be an other example of what this
architecture is all about.
http://en.wikipedia.org/wiki/Arcade_(architecture)
However, the articles on wikipedia are pretty poor. I suspect that
footway=arcade would actually be the best description if I remember
correctly the definition.

+1 (the English one at least, also the 2 last pictures are not typical
for what architects call an arcade, but they refer to the commercial
habit to describe shopping-centres and passages as arcades, which
might be good advertisement but is not correct in terms of
construction).

 I suspect that
 footway=arcade would actually be the best description if I remember
 correctly the definition.
yes, I agree for the example in the picture, but be careful: if the
way is not covered/formed by arches or vaults (round), it is not an
arcade (e.g. ancient Greek stoa). BTW: you can also find lots of
arcades in Bologna, Italy (I guess more than half of the historic
center has footways like this).

cheers,
Martin

 Arcade may be better than colonnade, but arcade is definitely in more
 common usage in the UK for a pedestrian route through a block with
 shops on both sides, so it will be slightly misleading. However I
 suppose the position next to a road makes it clear that it's one-sided.
  
 Richard

True, but again we are not just mapping for UK. I agree that it has a
different meaning in different part of the world. In my hometown you can
see the arcades look like this:
http://kamizole.blog.lemonde.fr/files/royale11.jpg
It is also the case in Tours in France, in the center. As someone
mentioned before, the arcade seems to be in use in Italy too. It would
be nice to have different people from different countries to chime in so
we can ascertain if the usage is right or not.
Using colonnade won't help as it is clearly a different kind of
structure in the first place.

IMO it's a simple sidewalk. So:

highway=* + footway=both/left/right
