Four months after shutting its doors, the Museum of Modern Art reopens today with 100,000 square feet of additional space. The $450-million renovation has been ongoing for four years, but the museum didn't need to close entirely until June 15.

Diller Scofidio + Renfro collaborated with Gensler on the project, which added 40,000 square feet of gallery space, a new lobby, an expanded ground floor, and a creativity lab. A new studio at the heart of the museum will feature live programming and performances that "react to, question, and challenge histories of modern art and the current cultural moment." The street-level galleries on the ground floor will be free for all visitors to view. There will also be a new restaurant, called The Carroll and Milton Petrie Terrace Café.

The new opening exhibits include:

• Sur moderno: Journeys of Abstraction

• member: Pope.L, 1978-2001

• Betye Saar: The Legends of Black Girls Window

• Private Lives Public Spaces

• Artists Choice: Amy Sillman- The Shape of Shape

• Heague Yang: Handles

• Surrounds: 11 Installations

Vans, UNIQLO, IZIPIZI and PLEATS PLEASE also collaborated with the museum for new products.

The museum is now open from 10 a.m. to 5:30 p.m. on Saturdays through Thursdays. Hours extend to 9 p.m. on Fridays for UNIQLO Free Friday Nights.
