From American Scenery, 1854 (almost exactly a century after the event depicted here). —Young Washington’s raft capsized on the way over, and he nearly drowned. He could have just used the Fortieth Street Bridge, but George had to do everything the hard way.
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).
The Monongahela is still very much a working river, and barge trains like this are a common sight. This one is empty and going upstream. Somewhere up there these barges will be filled with coal and come back downstream with their loads.
The boat that pushes the barges from behind is called, defying common sense, a towboat (corrected from “tug,” thanks to the helpful comment of a kind reader). Working on the barge trains is a dangerous business, but river culture has its own romance, with strong traditions passed on through the generations that most of us who spend our days on dry land know nothing about.
