Ground has broken on a new $180 million, multi-phase plan to expand the Texas Health and Human Services Commission’s John H. Winters Building, located at 701 W. 51st St., Austin, across from the Triangle mixed-use development.

The project includes the addition of a two-structure office, 406,000-square-foot office and 1,850-vehicle parking garage.

Construction on the two-building office and parking complex began in June, and it is scheduled to open in 2021.
