We don’t see many art openings at 10 a.m. ’round here; that always feels a little early for cheese cubes. But this Saturday, 10 a.m. is just when Pittsburgh’s newest major public artwork, “The Workers,” formally debuts.

The sculpture, by Tim Kaulen and the Industrial Arts Co-op, honors the mill workers of Pittsburgh past. The artwork sits in South Side Riverfront Park, just upstream from the site of the old J&L steel mill.

“The Workers,” 15 years in the making, was crafted from salvaged metal in a space just across the river in Hazelwood, on another patch of the vanished steel complex.

Here’s a short video CP posted, shot at an informal Sept. 1 event held shortly after the sculpture was first installed.

The artists and their collaborators (of whom there are many) will be on hand at 10 a.m. this Saturday. The site (accessible by taking South 18th Street toward the river) is adjacent to the South Side park’s dog park.

Attendees should RSVP at publicartpittsburgh.org.
