Was just thinking about this recently, as I travelled down a road which is 
one-way to motorists, but two-way to cyclists.

Or that one-way tunnel in London which changes direction in the 
morning/evening rush-hours.

And (not quite as on-topic), a road which is private, but also a footpath.  
Lots of possible combinations to consider when deciding whether routes can be 
used.
