In a prior post someone mentioned that there are going to be some extensive upgrades of the Gate / Town Center Pkwy intersection.
But the biggest planning issue they are going to face is the Gate Parkway off ramps on JTB. They already face chronic backups, where in some cases it is dangerous.
If / when Ikea comes around, that will cause further problems on Gate.
Town Center is now on its 25-30 year life cycle. Around 2030, Nocatee Town Center will start draining off people tired of the traffic hassle.
