Wow, nice find. That is a huge charging site! I'll have to visit soon.
Tesla's site is stating Q4 2022 opening now. Probably any day. Electrify America is not showing their chargers as live in their app yet.
Vehicles will likely route to Hancock/Roscoe interchangeably based on load during busy holiday times. 250kW in Hancock will help move things along nicely too. Roscoe gets clogged up during Thanksgiving/Christmas.
odd layout. easy to miss. one-way loop to access. make sure to enter on western-most side of loop. i missed first time and observed another tesla driver do same. easy walk to "old bat factory" for eats and biobreak.
