The Kennedy Center is a few dollars closer to making its ambitious expansion project a reality. Forty million dollars, to be exact.

The performing arts center announced today that it has raised an additional $40 million for a project that will add 60,000 square feet of rehearsal space, classroom space and multipurpose rooms, as well as gardens and an outdoor video wall for simulcast performances.

The total fundraising goal is $125 million: $100 million for construction and development, and $25 million for programming initiatives. Thus far, the Kennedy Center has raised $90 million, including a $50 million lead gift from chairman David M. Rubenstein. A “significant” portion of the new $40 million donations came from Michael and Noémi Neidorff and the Centene Charitable Foundation. Micahel Neidorff serves as co-chair of the campaign.

Here’s what that money will go to.

The Kennedy Center’s expansion project will be constructed south of the existing facility and will include rehearsal space as well as dedicated classroom space and multipurpose rooms for the Center’s extensive arts education programs. Public access spaces will include gardens which will fuse the Kennedy Center with the landscape and river and an outdoor video wall upon which simulcast performances and other multimedia events may be projected. The exteriors will utilize translucent Okalux, glass, and Carrara marble, the same Italian marble which clads the original facility.

Groundbreaking is expected to take place late next year, and construction is scheduled to end in 2017.
