Aren't they repurposing a large parcel of land in that area, to make way for a new apartment and retail development?
Increased traffic/congestion might be the only concern I'd have for that area, which is highly desirable, convenient, well groomed, and safe. Colonel
As to air pollution, I wouldn't give it a second thought; nor is that area close to any other potential nuisance (e.g. landfills, etc.).
Last but not least, that location is reasonably close to one of CLT's nicest parks:

Hope all works out with your move
