CHICAGO (WLS) – Construction of the University of Illinois' new complex, known as 78 for its Discovery Partners Institute, has been halted and DPI has withdrawn from the site.

Preparatory work for the 72-hectare site had begun, and now its future is unclear.

“We were part of their plans. We had provided a lot of input and then they said that as we moved forward, they had identified their contractors that they would begin construction on,” said Debbie Liu, a resident and member of the 78 Community Advisory Council.

Liu said she was shocked and disappointed that DPI was withdrawing; It was intended to be an anchor for the 78ers' technology center.

“The design of Building 78 began seven years ago, and so much has changed since then,” said U of I System President Tim Kelleen.

In a telephone interview, Killeen said moving its physical presence from 78 to the planned Quantum and Microelectronics Park on the South Side made more sense as DPI moves into the fast-paced and evolving world of quantum computing, digital transformation and artificial intelligence have along the lake shore.

“With this new approach, we can move quickly and truly help Illinoisans create jobs and gain access to technologies that will impact the entire economy,” he said.

The 78 is located on the South Branch of the Chicago River between the South Loop and Chinatown. A written statement from developer Related Midwest reads in part: “While we were disappointed to learn of DPI's decision to leave The 78, the departure opens up opportunities for new partnerships and site configurations.”

Residents say they need to continue to be part of the site's future.

“I hope the development won’t take too long in the future, but I also want to make sure the development reflects the needs of the community,” Liu said.

Over the years, plans for 78 have evolved from office space, to a casino, then to a sports stadium, to a mixed-use building.

“I definitely think there should be some transparency and accountability for this site since it is also a TIF district,” Liu said.
