Logistically, I don't know if it's possible, but I'd love to see a flyover for the people exiting westbound from I-4 at Sand Lake -- one that squeezes between the Whole Foods property and the on-ramp to westbound I-4 (from Sand Lake) and connects into Turkey Lake there at that curve between Whole Foods and Wal-Mart. That, at least, would allow people to bypass that Turkey Lake/Sand Lake intersection -- if their purpose is to visit anything on south Turkey Lake Road (the hospital, Whole Foods, Wal-Mart, the condos, etc.).
Better yet, an off-ramp from westbound I-4 that works in tandem with the Beach Line exit, but allows you to exit onto Turkey Lake.
