Pittsburgh is both the "City of Bridges" and the "Robot City", and artist Glenn Kaino combines both identities into ARCH, a transformer sculpture commissioned for Pittsburgh's 250th by the Andy Warhol Museum. The giant robot is located at the corner of a parking lot on Seventh St. and Fort Duquesne Blvd. in the Cultural District, right across from the big, yellow Warhol Bridge (which seems like a distant relative). I took this photo of ARCH on my lunch hour. I think that he is more Autobot than Decepticon... He has a friendly countenance!
