The Sixth Street or Roberto Clemente bridge, one of the famous Three Sisters that span the Allegheny, glows in the late-afternoon sun. Beyond it, the increasingly cluttered skyline of the North Side.
Supposedly Pittsburgh is the only place in the world where you can see three identical suspension bridges in a row: the Sixth, Seventh, and Ninth Street Bridges over the Allegheny, now named for Roberto Clemente (because the Sixth Street Bridge leads to the ball park), Andy Warhol (because the Seventh Street Bridge leads to the Andy Warhol Museum), and Rachel Carson (because we’re really proud of Rachel Carson).
This bridge on one of the bridle paths in Schenley Park is actually made of concrete covered with tufa (a kind of underwater limestone formation), but it looks as if it simply grew over the Phipps Creek. It was built in 1908, and over the century since has had ample time to grow a lush coating of moss.
