The U.S. Senate on Tuesday confirmed two federal representatives to the board of the Metropolitan Washington Airports Authority, which oversees Dulles International Airport, Reagan National Airport and the $6 billion Dulles Rail project.

William Shaw McDermott, a Boston-based lawyer, and Nina Mitchell Wells, a former New Jersey secretary of state, will replace Charles Snelling and Bob Brown. Snelling died in March, and Brown left the board in November when his term expired.

The two newcomers will join several other fresh faces on the board, as several members' terms have expired and two others have resigned in the past year.
