K6 stops


History
K6 originally began operating as part of the Capital Transit Company "New Hampshire Avenue" Bus Line in 1964, between White Oak Shopping Center in White Oak, Maryland, and Metro Center in Downtown Washington D.C. mostly operating along Columbia Pike, New Hampshire Avenue, the White Oak FDA/FRC Building, and North Capitol Street NW. K6 eventually became a WMATA Metrobus route on February 4, 1973, when WMATA bought all four failing private bus companies that operated throughout the Washington, D.C., Metropolitan Area and merged them all together to form its own Metrobus System.

1978 Changes
On February 19, 1978, after Fort Totten station opened, K6 was truncated to only operate between the White Oak Shopping Center and Fort Totten station. The remaining segment of K6's original routing between Fort Totten and Metro Center was replaced by WMATA's brand new route K4, which was designed to operate between Fort Totten and Metro Center.

2013 Changes
On December 29, 2013, route K6 discontinued all service to the Food and Drug Administration and instead remained straight along New Hampshire Avenue. Service would be replaced by route K9 which was extended from Northwest Park.

2016 Changes
When the Takoma Langley Crossroads Transit Center opened on December 22, 2016, the K6 was rerouted, along with several other Metrobus, Ride On buses, Shuttle UM and TheBus routes, to serve the newly opened Transit Center. Route K6 would serve Bus Bay A (Northbound) and Bus Bay G (Southbound) alongside route K9.

2023 Changes
On June 25, 2023, northbound K6 trips was rerouted to Stuart Lane and Lockwood Drive to terminate in White Oak, service along Old Columbia Pike and inside of White Oak Shopping Center was discontinued.
