Good afternoon, KhVernon.
Here is a map of the current Huntersville City limits as well as the Sphere of Influence, which includes areas that are eventually going to be annexed by Huntersville. http://ww.charmeck.org/Planning/ZoningMaps/Zoning%20Grid.pdf NC 73, Asbury Chapel, Huntersville Concord Rd, Beatties Ford Rd all provide decent access to freeways and have neighborhoods off of them that can have less traffic.
NCDOT regularly surveys traffic and gets traffic counts for the major roads in Charlotte and Concord. THe link is here: http://www.ncdot.gov/travel/statemapping/trafficvolumemaps/urban/
Where I'd advise you look would depend on the time and locaiton of your primary travel destination. If you take NC 16 to NC 73 you can end up on the western edge or northwest corner of Huntersville without going up 77. If you have a full time agent with a Masters degree in Planning with Finance and over two decades of experience, working for you, you will likely do better in negotiations. I'd be pleased to provide that service. If you appreciate this answer, please give it a thumbs up, or if this was the most helpful answer, please say thanks with a best answer click.
