No. it doesn't. Highway is the primary tag. It usurps sub-tags which are 
merely adjectives of the primary.
When it has been completed it will be designated for use by bicycles.

Route relations should be aware of tags on ways. access=no can be used 
in part to indicate road works.
Just because a way may be inaccessible to bikes doesn't mean it's not 
still officially regarded as a cycle route (the NCN ref won't be removed)
