K Street provides a major east–west thoroughfare for traffic through Washington, primarily from [[Mount Vernon Square]] to [[Whitehurst Freeway]]. The street continues through Georgetown under the Whitehurst Freeway; however most westbound traffic exits to the freeway. A portion of the street travels in a tunnel underneath [[Washington Circle]], allowing through traffic to avoid the circle. Portions of the street are divided into both "local" (or [[frontage road|service]]) lanes and "express" lanes in both directions.<ref>{{cite web |url=http://greatergreaterwashington.org/post/3087/k-street-transitway-options-balance-buses-bikes-cars-and-loading/ |title=K Street Transitway options balance buses, bikes, cars, and loading |author=David Alpert |date=July 30, 2009 |work=Greater Greater Washington |access-date=January 5, 2012 |archive-date=October 12, 2011 |archive-url=https://web.archive.org/web/20111012052152/http://greatergreaterwashington.org/post/3087/k-street-transitway-options-balance-buses-bikes-cars-and-loading/ |url-status=live }}</ref>

===Proposed===
The [[Washington Metropolitan Area Transit Authority]] has been studying the conversion of K Street into part of a proposed [[Bus rapid transit|busway]].<ref>Halsey III, Ashley. "Navigating a Bus Path For K Street - Again." ''Washington Post.'' August 30, 2009.</ref> The route would begin at [[Georgetown University]], cross [[Downtown Washington, D.C.|downtown]] Washington on K Street, switch to [[Massachusetts Avenue (Washington, D.C.)|Massachusetts Avenue]] at [[Mount Vernon Square]], and end at [[Washington Union Station]]. The [[DC Circulator]] provides service along most of the proposed route, although it must share the right of way with other vehicles.

A streetcar line spanning from 26th Street NW to the [[H Street Line|H Street line]]'s terminus at Union Station is planned as the next phase of [[DC streetcar|DC's streetcar expansion]].<ref>{{cite news |title=From seedy to sought-after: D.C.'s Mount Vernon Triangle becoming urban village |url=https://www.washingtonpost.com/wp-dyn/content/article/2010/01/28/AR2010012804734.html?sid=ST2010012902292 |newspaper=Washington Post |date=January 30, 2010 |access-date=January 5, 2012 |archive-date=March 4, 2016 |archive-url=https://web.archive.org/web/20160304212003/http://www.washingtonpost.com/wp-dyn/content/article/2010/01/28/AR2010012804734.html?sid=ST2010012902292 |url-status=live }}</ref>

A proposal announced on April 7, 2022, would redesign K Street between 12th and 21st Streets, N.W. The proposal would remove the service lanes in favor of dedicated bus and [[bike lane|bicycle lanes]]. Under the proposal, construction would begin in the spring of 2023.<ref>[https://www.washingtonpost.com/transportation/2022/04/07/dc-k-street-transitway/ "K Street makeover will bring dedicated bus lanes, remove service lanes"] {{Webarchive|url=https://web.archive.org/web/20220408004714/https://www.washingtonpost.com/transportation/2022/04/07/dc-k-street-transitway/ |date=April 8, 2022 }}, [[The Washington Post]], April 7, 2022</ref>
