In this article about a new gas station opening next to RDU airport, it mentions the current Sheetz (1600 Aviation Pkwy) will be demolished and rebuilt. (Possible paywall so I've included the quote below)
This permit simply mentions the Tesla chargers included as part of the construction. Interestingly, a separate permit was filed for "new EV Charging Canopy Structure with roof mounted Solar panels."The RDU Galleria will open just as the Sheetz convenience store nearby prepares to close. The company plans to demolish the existing 16-year-old building and build a reconfigured one that’s a third larger. In an email, Sheetz spokesman Nick Ruffner said the new store will “include a restaurant-style experience with self-service kiosks, additional seating both inside and outside the store, a drive-thru, a new Tesla charging station and more.” The company hopes to reopen by the end of the year.
