Yes, sometimes the street signs don't say North Academy Ave or South Academy Ave.
The reason for this is due to the way the road network grew years ago. The street addresses start at 0 or 100 and increment in one direction. Then there is a need to extend the road in the other direction but they don't want to re-number every home and business. So they start up a 'new' road heading the other direction and make it North Academy Ave one direction and South Academy Ave in the other direction. Generally where they meet the addressing starts at 0 or 100 and increments heading away from the intersection.
So yes, generally these street names are valid.
