Pittsburgh, Pennsylvania: 20-Foot-Tall Steelworkers of Iron

Two robotoid metal steelworkers stand 20 feet tall and are made from over ten tons of scrap metal.

Two metal steelworkers each stand 20 feet tall and are made from four tons apiece of scrap metal, mostly steel and iron girders from a nearby bridge. They stand as if pouring molten steel from a 15-ton ladle -- salvaged from a local steel mill -- which now tips into a bed of flowers. Titled "The Workers," the giant angular metal men are meant to forge a connection between Pittsburgh's old labor force and its new artistic denizens.

The statues, which look like beta test version Decepticons, took 15 years to complete, mostly because their costs ballooned from $25k to $200,000. They were finally moved into position in Southside Riverfront Park on Labor Day 2012.
