LINCOLN, Neb. (AP) — The University of Nebraska’s new research park is ready to open, despite lingering challenges and questions from lawmakers who were asked to spend more on the project.

The Nebraska Innovation Campus will host an open house on Friday, one day after a ribbon-cutting with Gov. Pete Ricketts, University of Nebraska President Hank Bounds and other dignitaries.

The park is designed to promote partnerships between businesses and university researchers. It has attracted local and international companies as tenants, but others have backed out because of rent costs and competition from other areas.

Nebraska lawmakers are also looking to ensure the university has a plan to measure the project’s success. State officials approved $25 million for the project in 2011, but university officials returned this year to request another $25 million.
