Crossing Roberto Clemente Bridge

From downtown Pittsburgh you can walk across one of three bridges to get to PNC Park....this is the 6th Street bridge aka Roberto Clemente Bridge.  The pic doesn't do it justice, it's quite a lovely walk over the Allegheny River.  To the left of this photo is the Ohio River.  PNC Park in the background.  Okay, triva buffs, what famous Pittsburgh-born artist is the 7th Street Bridge named after....ANDY WARHOL.
