I went through the aerials, and Esri World Imagery Clarity Beta shows there used to be buildings on both sides and went originally connected to West Avenue A.  This would have made the original use case an alley.

Some years ago the buildings were removed, so i don't know if the Alley classification stands but it's the best I could come up with.  You can always remove the alley tag and just label it as a service road cause I can't see anybody needing to know about it.

I also added a noname=yes tag.
