Description:
A colossal machine called the "Lady Bird" is boring a huge tunnel under Washington, D.C., to channel storm water for treatment, keeping runoff out of the city's notoriously polluted rivers. The $30 million machine is named for Lady Bird Johnson, who, as First Lady of the United States, had advocated for cleaner rivers around the nation's capital.
