While the hospital's entrance undergoes a renovation, the students are trying to make the fence more appealing.
More than 800 students - kindergarten through 8th grade - donated their artistic talents and enthusiasm to the project named, "Painting the Pathway to Healing."
"I just think it's awesome," said Sunnyslope School art teacher, Liz Meltzer. "We didn't know how it was going to shape up but it's just amazing. It's just evolved into something really cool."
Brian Thompson, with DPR Construction, said this is the third time his company has participated in a project like this.
"It takes certain projects with certain owners," said Thompson. "It's gotta be a right fit. It's something we love to do. This has gotta be the coolest construction wall in Phoenix."
The artwork is intended to reflect the healing connection between nature and the human spirit.
A lot of the Sunnyslope School students who are working on this project were born at John C. Lincoln North Mountain Hospital.
The school plans to take a piece of the artwork back to the campus when the wall comes down.
The wall painting project is expected to be completed on Friday. The hospital renovation is scheduled to be finished by November.
The reconstruction project for the John C. Lincoln North Mountain Hospital was made possible last year, when David Lincoln and his family - descendants of John C. Lincoln - donated $4 million to upgrade, renovate and recreate the entrance, to create the hospital's new "Pathway to Healing."
The project is intended to be a visual representation of high quality health care.
