Basically there is no good way to get to the North side above Polaris. I drive 71-gemini-Polaris-Old State every single day. It's a parking lot some days, and others not too bad. I'm there right around the 5:15 pm timeframe. I believe there is a proposed exit either at Big Walnut or Cheshire someday. If this happens then that road needs double lanes from 71 to 23 on that rd. Dreaming though...
Also a proposed extension of Gemini to Worthington rd is in the works. A developer is wanting to build up that area where the old Polaris Amphitheater is. Doubt it gets approved.
