Once last look at this certain corridor, here's what many web-based maps consider to be the epicenter of the College Station: University and Texas Avenue. At this prominent corner (425 Texas Avenue South) is an Exxon station, built in 1994.
The previous gas station was a Shell, likely built in the late 1970s, which replaced an even older gas station on the site (we'll have to find that one later). In the post for the Plaza Hotel, a video is linked that shows the intersection as it looked in the early 1980s, you can see a shot of the smaller Shell (logo) sign here (annotated version by "AggiePhil") as well as a black and white night picture of the sign from the Daily Texan (thanks to "Aggie Network" from TexAgs for tipping me off to this).
In the picture above, you can see the Jimmy John's and the former Pizza Hut, both of which have been previously covered.
UPDATE 05-19-2023: I have finally (by myself, no one sent it) acquired a picture of what was previously only described (the date by the way is July 7, 1989). Minor other edits have been made.
