If the use of the cycle is required, and the only other path is the  
road, then putting bicycle=no on the road will cause routing  
algorithms for cyclists to push the cyclist to the adjacent cycleway.  
When a cycle specific map gets rendered, then it could grey out the  
road, with the cycleway highlighted. I think this is a better way to  
tag it, otherwise routing will not know which road cyclists are not  
meant to use.

I would also like to see the value bicycle=dismount, for short  
sections where cyclists have to dismount as part of the cycle network.
