The first portion of the system opened March 27, 1976, with available on the Red Line with five stations from Rhode Island Avenue to Farragut North, all in the District of Columbia. All rides were free that day, with the first train departing the Rhode Island Avenue stop with Metro officials and special guests, and the second with members of the general public. Arlington County, Virginia was linked to the system on July 1, 1977; Montgomery County, Maryland, on February 6, 1978; Prince George's County, Maryland, on November 17, 1978; and Fairfax County, Virginia, and Alexandria, Virginia, on December 17, 1983. Underground stations were built with cathedral-like arches of concrete, highlighted by soft, indirect lighting. The name Metro was suggested by Massimo Vignelli, who designed the signage for the system as well as for the New York City Subway.
