The National Park Service says the White House Visitor Center is scheduled to close this weekend for more than a year for rehabilitation work.

Stephen Whitesell, regional director of the park service, says the center at 1450 Pennsylvania Avenue will close at 4 p.m. Sunday for the work, which is expected to last about 15 months.

Improvements to the visitor center will include interactive exhibits, a model of the White House, a museum gallery and an improved bookstore.

A temporary visitor facility will open July 28 at the Ellipse Visitor Pavilion near 15th and E streets. It will remain open until the work is completed.
