Washington just cut the ribbon on the Silver Line, a new rapid-transit line connecting the center of D.C. to northern Virginia.
The 11-mile line opened for business this weekend and attracted over 50,000 riders. It includes five new stations, many through the city of Tysons Corner. When an extension of the line opens in about four years, the Silver Line will reach past Dulles Airport, and include a station at the busy airport.
The Silver Line is D.C.'s sixth rail line, and the city's first new line in a decade. The Washington Metro is the nation's second-busiest transit system after New York's. Read more here and watch a news report on the opening below.
