On the south side of Tanque Verde Road, just east of Catalina Highway, five curved concrete forms coated with dirt and rocks stand in a circle.

Each of the trough-shaped pieces was cast directly from the Bonanza Wash (the sculpture’s earth coating came directly off the bottom of the channel) and positioned to resemble a large vessel.

“You’re seeing the impression of the actual wash,” said Nancy Cole, with the Pima County Transportation Department.

The $170,000, 20-foot-tall sculpture is the public art component of the ongoing Tanque Verde Road widening, scheduled for completion by fall.

The recently completed artwork is a tribute to water, which is the very reason a community developed there in the first place, says a narrative describing the concept behind the sculpture.

As part of the widening, that wash will be rerouted. Residents who live nearby were sad to see it go, so they wanted a sculpture that would serve as a reminder of the natural landscape, said Sally Krommes, with the Tucson Pima Arts Council.
