I support David's reply - so far as England and Wales is concerned. A
bridleway is a legally defined way that should be so signed on the ground
(by law where it joins or intersects a motor road). Cyclists are allowed to
use bridleways (except where explicitly forbidden by a local ordinance - a
rarity). There is no formal definition of a cycleway but the word seems to
have (at least) three meanings: (a) a dedicated way for cyclists alongside a
motor road and so signed on the ground, (b) a dedicated way for cyclists -
often alongside a way for pedestrians or sometimes shared with them -
usually paved and in urban areas - and so signed on the ground, (c) a
medium- to long-distance route for cyclists designated by the charity
SusTrans and often using other ways, e.g. quiet motor roads, bridleways,
towpaths, etc. but rarely (if ever?) designated only for cyclists. Where
there is any doubt from signage on the ground I would use highway=footpath,
=bridleway, =byway as recognisable designations and add foot=yes,
bicycle=yes, etc. The recent trend also to use a designated= tag (as
discussed about a month ago in this list) is helpful as regards legal status
drawn from any non-copyright database. The existing tags surface= are
helpful to describe condition of the surface and thus suitability for e.g.
cyclists. Other options in wide use are tracktype= and (I'm not getting into
this one!) smoothness= (;>).

If it says bridleway, then surely it is a bridleway, since these tags are
informed by evidence on the ground, not a statutory database of legal
rights. How do you _know_ it is a cycleway if the sign says otherwise?

If you're a horse rider, you might well be just a peeved the other way by
you changing "their" bridleway to a cycleway.

In the UK bridleways are legally accessible by cyclists, so if you're trying
to use this in a context of cycling, why not just recognise bridleway as
something you can cycle on, or change the access tags to make this clear.
You could also set the surface tag to indicate that it is a paved surface
and thereofre better suited to cycling than most bridleways (if it is, of
course).

If you're just worried that mapnik *shows* it as a bridleway, then surely
Mapnik is right to do so in this case if that's what the sign says.
