The Legislative Reorganization Act of 1946 brought significant reforms in committee staffing and operations. These increased Congress’s need for hearing rooms and staff offices. Four new buildings helped to meet the demand: the Dirksen and Hart Senate Office Buildings (opened 1958 and 1982) and the Rayburn and Ford House Office Buildings (opened 1965 and acquired 1975).
Due to adverse weather conditions, the Capitol Visitor Center will open two hours late, at 10:30 a.m. Capitol tours will begin at 10:40 a.m.
Due to a special Joint Meeting of Congress taking place in the Capitol on Tuesday, March 3, the U.S. Capitol will be closed to tours until approximately 12:30 p.m. on that day. The Capitol Visitor Center will remain open throughout the day, 8:30 a.m. to 4:30 p.m., and guided tours of the Capitol Visitor Center will be available while the Capitol is closed.
