Arby's sole College Station location (and Bryan, too, though they briefly had one of their own) was built in 1982 at 1800 Southwest Parkway with a new addition around 1999 that added a large, modern facade (I remember being very impressed with the remodeled restaurant, but I don't think the restaurant seating was enlarged). Arby's has stayed put even with major closures which did a number on the Houston area, some looking like this or even newer, and this store has not received the newer logo yet (thankfully). I don't recall what the old restaurant looked like, but I'm pretty sure it was closer to this one in San Marcos (since demolished and replaced with a Raising Cane's), except with a more brown-ish colored roof.
UPDATE 03-12-2022: A few fixes. Tax data says it opened in 1982, but BCAD says 1984. I'll change it to 1982 as that tends to be a bit more reliable.
