Company Names, addresses, dates¹:
  Pepsi Cola Bottling Co of Arlington VA
  Old Dominion Pepsi Cola Bottling Co of Arlington VA (c.1948-??)

Notes:
A Washington Post article from Sept 21, 1955 said that Russell M. Arundel owned the Old Dominion Pepsi bottling company in Arlington. He established a Long Island NY Pepsi bottling company in 1944. He sold the Virginia firm to the parent Pepsi company in 1948 to concentrate on the Long Island NY plant¹.

A Washington Post article from June 15, 1947 described construction of the Old Dominion Bottling Co in Arlington VA at Four Mile Run and Oakmont Street. I think this may have been a misprint, and they meant "Oakland" Street, since "Oakland" Street is a cross street for Four Mile Run, and "Oakmont" Street is in Alexandria. Note that there was indeed a Pepsi bottling plant on Oakmont Street, but that is in Alexandria, not Alrington. The article said the plant was expected to be ready in 1948².

Based on the two articles described above, I really don't know what years Pepsi was being bottled in Arlington. My guess is that the Arlington plant was completed in 1948, and made bottles for the Arundel's Long Island company for a while (one of the bottles below says "LONG ISLAND CITY, N.Y. BOTTLED BY OLD DOMINION PEPSI-COLA BOTTLING CO"), and then Arundel sold the company, which probably continued to bottle Pepsi for a while, but I don't know how long. There does not seem to be a Pepsi plant at Four Mile Run & Oakland Street today.
