This Day in History: 1942-07-20

As an emergency wartime measure, photography was forbidden on the George Washington and Staten Island bridges, and in and around the Holland and Lincoln Tunnels. The bans included still and motion picture photography on or from these structures and was being enforced by police and by special signs. Some film had been confiscated from over-enthusiastic hobbyists. Sabotage by spies was feared. (Bristow)
