The Macombs Dam Bridge sits in the opened position while the tail end of CSX Q701(21) snakes along the shores of the Harlem River on the Oak Point Link in The Bronx, NY on March 22, 2022. While CSX traverses the Oak Point Link daily, the Macombs Dam Bridge opens very rarely. Most vessel traffic on the Harlem River usually fits under this bridge in the closed position. Strict Coast Guard regulations prevent openings during most hours of the day, which is why the rare openings mostly occur at night.

The Macombs Dam Bridge is a camelback swing bridge across the Harlem River in New York City, connecting the boroughs of Manhattan and the Bronx. The bridge is operated and maintained by the New York City Department of Transportation (NYCDOT).
