ANN ARBOR, Mich. — The University of Michigan's new Mott Children's and Voigtlander Women's hospitals are set to open their doors to the public for the first and only time.

There will be an open house from 10 a.m. to 5 p.m. EDT on Sunday at the 1.1 million square feet, $754 million facility.

Patients will be moved Dec. 4 from the old to the new Mott

On Tuesday, officials showed off the features of the complex that they boast is the largest construction project in the state.

The bells and whistles include a "3D Woodson" mobile app that allows visitors to produce a life-size image of Charles Woodson. He won the Heisman Trophy and national championship at Michigan before going on to become a Super Bowl-winning cornerback for the Green Bay Packers.
