This was the last "Highway Patrol" episode to be aired, although it was not the last to be filmed. That distinction belongs to "Fire" (episode No 4.38).
Los Angeles City Hall is shown on the last aired episode of Highway Patrol as Dan Mathews and Sgt. Williams race to the motel room to catch the male and female felons. Los Angeles City Hall was completed in 1928. At 454 feet high and with 32 floors, was the tallest building in Los Angeles up until 1968.
