The Putnam Bridge was a swing bridge that spanned the Harlem River and the adjacent tracks of the New York Central Railroad in New York City. The bridge connected Harlem in Manhattan to Concourse, near the current location of Yankee Stadium, in the Bronx. It carried two tracks of the New York and Putnam Railroad, and later the 9th Avenue elevated line of the Interborough Rapid Transit Company (IRT), as well as two pedestrian walkways outside the superstructure.
