Folder: S.F. Bridges-Bay-Emergency Services.
On back: "In the past year more than 7,500 motorists have made use of the San Francisco-Oakland Bay Bridge tow car service, Sam Conway, span roadside service man, tells Marian Conway (no relation). The red-colored boxes, placed at convenient intervals along the north side of both decks, are for the convenience of Bay Bridge patrons stalled on the span for lack of gasoline, flat tire, motor trouble or accident. By opening the box door and smashing a glass dial, the motorist automatically places a call into the bridge garage on Yerba Buena Island. Within an average of three minutes a tow car comes to his aid, equiped for any emergency. This is the first time a fire alarm system has been adapted to such purposes."
