There definitely should be a supercharger in Statesville to cover the 77/40 junction, but the previously proposed location was pretty bad. Way out of the way for I-40 travelers who would have to travel way out of the way south on I-77.
Somewhere NW of the 40/77 interchange around Hwy 21 where all of the gas stations, shopping, food, etc is would be best for both 40/77 IMO. From 77 you just hop on 40 and don't even need to exit your lane to immediately get off on 21, and from 40 just take the exit. Getting back to either highway is just as simple. Not out of the way for either one, really, since that's a regular stop for travelers on both highways anyway. Alternatively, 77-S drivers can just jump off at 21 directly a couple miles before the 40/77 interchange.
Seems like a no-brainer location for a Statesville supercharger to me, really. Glad the previous target location never happened.
FWIW when i suggested this site to Telsa via the form I also submitted to Electrify America. Not sure if my suggestion mattered but looks EA has one coming in that location now. Looks to be at the walmart adjacent to cracker barrel
