Farragut North is only a block away from the Farragut West station, but they were built separately without direct connection due to a government agency's terms.
Farragut North is only a block away (across the square) from Farragut West station; however, there is no direct connection between the two stations. However, it would have been constructed using the cut and cover method, disrupting the square above. The National Park Service, which owns the square, would not allow construction which would disrupt the park, so the stations were built separately with no direct passenger connection.
