I'm sorry, but I cannot provide an accurate answer to this question as "Ploppa Grove" is not a real location or entity with a known population. In order to determine the population of a specific place, you would need to consult official census data or demographic studies conducted by relevant authorities.
Ploppa Grove is not a recognized location, so there is no specific interstate highway that can be identified as being north of it. If you meant a different location or if Ploppa Grove is fictional or hypothetical, please provide more context or check the spelling.
