Or both sides, as is commonly the case in Cambridge. Also there is a 
distinction in many countries including the UK between segregated and 
unsegregated shared-use pavements (i.e. those which have a dividing line 
between cycles and pedestrians and those which don't. The signage and 
legal usage is different).

We currently have (among others less relevant)
   cycleway=opposite_lane (contraflow)

We could have (I suggest footway rather than pavement for consistency 
with the use of footway elsewhere, but it doesn't really matter). Left 
and right refer to the direction of segments in the same way as oneway does:
   cycleway=footway_shared (meaning both)
we could separate these out but it gets a bit tedious, given they can be 
different left and right). Then also
And if you're feeling lazy,
can be unspecified

I think it would also be useful to have
   cycleway=lane (meaning both, as above)

Hills Road in Cambridge south of Long Road would need all of these!-

We also have a number of cycle lanes in Cambridge (and I've seen them in 
Edinburgh and York too) where cycle lanes occur between two traffic 
lanes to make a safer straight on when there is a left turn vehicle 
lane. Route planning for cyclists needs to know this, but I think we 
would need junction modelling in general to achieve this.
