I've heard rumors of the Beckley service area scheduled for replacement or extensive rebuilding within the next five years. The service plaza was opened in 1993 (and replaced an original Glass House).
Probably one of the best amenities that has been added in recent years, and a trend that I'm seeing being added at other service areas (i.e. along the New York State Thruway) are showers for motorists, RV drivers, and truck drivers - or for folks like me who camp at places with no amenities. The showers at Beckley were added several years back and typically cost about $7/shower, which is about half the price of a typical truck stop. The closest truck stop with showers is either Cross Lanes or Ripley to the north or well into Virginia to the south and east.
I am hoping that a rebuild includes more of a "food hall" concept or at least a place that's not nearly as dreary or barren, more parking for trucks and RV drivers, and Superchargers (or reliable high-speed EV charging ports). The truck parking facilities are completely maxed out pretty much every night, and the general parking area can be near capacity during the day. A lot of RV drivers will park in the lower area of the Tamarack, which allows it for overnight stays.
I am hoping that if this and others are rebuilt (Morton and Bluestone opened in 1991) that they will also offer showers and charging ports.
