Herndon (preliminary names Herndon–Monroe, Herndon–Reston West) is a planned Washington Metro station in Fairfax County, Virginia on the Silver Line. The station would be in the median strip of VA-267 adjacent to the current Herndon-Monroe Park and Ride parking garage and bus station, which is on the south side of the highway. This location is in Reston, but has a Herndon postal address. In anticipation of a future mass transit route in the Dulles Access Road median, in 1999 Fairfax County constructed a $20 million park and ride facility which includes a Fairfax Connector station that serves most bus lines in the Herndon and Reston areas as well as buses carrying commuters to the West Falls Church or other Metro stations daily. The existing facility is served by direct westbound on ramps and eastbound off ramps to SR 267. The existing parking garage has 1,750 spaces. The garage has drawn criticism because of alleged construction flaws. The garage will be expanded to 3,500 spaces for the Metro station.
The proposed Metro station will begin operation in late 2019 or in 2020. In the meantime, the Town of Herndon has initiated transportation oriented development of the land on the north side of the station. In turn, the Town of Herndon, on November 10, 2009, designated commercial, industrial and multi-unit rental residential properties within the town boundaries for inclusion in a special tax district to fund construction of Phase II of the Silver Line.
