SIOUX FALLS (AP) - A Sioux Falls group building a massive arch sculpture straddling the Big Sioux River has raised $2.4 million to complete the project.

SculptureWalk announced this week that the organization has commitments from donors to finance the remaining construction and the installation of the Arc of Dreams sculpture, the Argus Leader reported.

"We hit the $2.4 million level, which pays for everything - construction and installation and the plaza area," Jeff Hansen, SculptureWalk's media relations director.

The 285-foot-long stainless steel structure was originally scheduled for installation in Sioux Falls this summer, but was delayed due to a lack of funds and construction complications. The $2 million sculpture might not get to the city until this spring, Hansen said.

Zimmerman Metals, a metal works company in Denver, Colorado, is building the sculpture pieces and plans to transport them to Sioux Falls by semi-trailers once complete.

Moving those pieces during winter weather could be challenging, according to Hansen.

"As we stare at the weather that we know is coming, we're going to have to make some choices and decisions and see how much risk we want to take on moving it," he said. "You've got two things - the transportation and the installation. It's a two-week period to install."

The group wants to err on the side of caution, Hanson said.

The Arc of Dreams will stand 70 feet above the river once it's finished, representing the risks and uncertainty of pursuing dreams.
