Opened in 1940, this Safeway store at 228 Seventh Street SE in Washington DC managed to hang on until 1986. It was still profitable until the end; the need for expensive renovations was cited as the reason for its closing. The surrounding neighborhood was not happy about the closing and the city council tried unsuccessfully to delay it through legislation.
It’s a classic 1940s store, modernized probably in the mid 1960s. The Noe Valley store in San Francisco, closed in the mid 1970s and pictured below, was probably a fairly similar renovation. I’d love to have seen the interiors of these stores. It’s amazing they lasted as long as they did.
The SF location, by the way, managed to hang on for another fifteen years as a Bell Market after Safeway moved out. It’s now an unrecognizable Walgreens. I don’t know the fate of the DC store.
