Andy Warhol Bridge, also known as the Seventh Street Bridge, spans the Allegheny River in Downtown Pittsburgh, Pennsylvania and is the only bridge in the United States named for a visual artist. Named for the artist Andy Warhol, a Pittsburgh native, it is one of three parallel bridges called The Three Sisters, the others being the Roberto Clemente Bridge and the Rachel Carson Bridge. The Three Sisters are self-anchored suspension bridges and are historically significant because they are the only trio of nearly identical bridges - as well as the first self-anchored suspension spans built in the United States.
