It's the way it was done with the street name split a while back, though I 
acknowledge that it isn't an identical situation, since we ultimately 
decided the direction was not part of the street name. In this case, the 
direction is an important part.

I would not be averse to something like:

exit_to="CA-247 South"

OR

exit_to_root="CA-247"
exit_to_dir="South"

Consumers that have evolved can use the second form if it is found, or the 
first if it is not. Older consumers can use the first form. Users that 
choose not to use the second form can use the first form and it will work 
with both old and new consumers.
