247 Canal, 1930.

The six-story tenement building at the corner (no. 247) is no longer standing and has been replaced by an ad hoc single story souvenir shop. The traffic tower is, of course, no longer extant either.

The traffic towers of New York were attempts at safety and traffic control on city streets that were becoming gridlocked and dangerous with automobiles. In 1920 Dr. John A. Harriss, a millionaire doctor, designed the first permanent traffic lights in New York, which were a small wood shed on a steel frame. From inside the shed a police officer could change the signals, allowing for traffic to flow safely in each direction. More traditional traffic lights (red, yellow, green) began to be installed in the late 1920s, but this corner at Lafayette and Canal had not had their tower replaced when this photo was taken in 1930.
