The Roosevelt Island Bridge is a tower drive, vertical lift, movable bridge across the East Channel of the East River between the borough of Queens and Roosevelt Island, New York City. The span length is 418 feet. It was known as the Welfare Island Bridge when it was first opened to traffic in 1955.

The bridge is the only means of vehicular access to Roosevelt Island. Prior to construction, the bridge carried two 17-foot lanes of vehicular traffic and a 6-foot sidewalk. The bridge is used by both pedestrians and vehicles with increased volume during rush hours. The Queens approach begins at the intersection of Vernon Boulevard and 36th Avenue.

Roosevelt Island is home to a residential community and a number of parks and landmarks. At the island’s southern end, the Louis Kahn–designed Franklin D. Roosevelt Four Freedoms Park offers public programming and family-friendly events.

There is also the Renwick Ruin, a former smallpox hospital; the Octagon tower, the remnants of an insane asylum; and, on the northern tip, a 19th-century lighthouse anchoring a park from where visitors can get wide-angle views of NYC.
