On Tuesday, October 21, 2025, Pittsburgh City Council unanimously granted a historic designation to the city’s Three Sister Bridges. Named after Pittsburgh icons Roberto Clemente, Andy Warhol, and Rachel Carson, these are the only known trio of identical self-anchored suspension bridges in the world.

Pittsburgh’s skyline is renowned for its breathtaking views, and none are more iconic than the Three Sisters Bridges: the Roberto Clemente Bridge, the Andy Warhol Bridge, and the Rachel Carson Bridge. As the only trio of nearly identical, side-by-side bridges in the United States, they are fittingly referred to as the Three Sisters. However, each bridge carries its own distinct identity, named to honor influential Pittsburgh residents who left a great mark on the city and beyond.
