It's not even close to identical. It's very rare to have two parallel 
streets with the same name except for a different directional prefix 
(and in those cases the directional prefix should be part of the name). 
On the other hand, it's very common to have two consecutive exits for 
each direction of a road.

The question is still what benefit there would be to splitting it.
