'''Interstate&nbsp;266''' ('''I-266''') was a proposed loop route of I-66 between [[Washington, D.C.]], and [[Arlington County, Virginia]]. D.C. officials proposed designating the route Interstate&nbsp;66N, a move opposed by [[AASHTO]]. In Virginia, I-266 would have split off from I-66 just east of the present [[Virginia State Route 124|SR&nbsp;124]] (Spout Run Parkway) exit. From there, it would have followed an expanded Spout Run Parkway, crossed the [[George Washington Memorial Parkway]], and crossed the [[Potomac River]] across a new bridge that would have been called the [[Three Sisters Bridge]]. Upon entering D.C., it would have followed [[Canal Road (Washington, D.C.)|Canal Road]] and an expanded [[U.S. Route 29 in the District of Columbia|US&nbsp;29]] (Whitehurst Freeway) to rejoin I-66 at [[K Street (Washington, D.C.)|K Street]]. I-266 was canceled in 1972 in the face of community opposition during Washington, D.C.'s [[Highway revolt|freeway revolts]].<ref name=rttf>{{cite web|url=http://www.roadstothefuture.com/DC_Interstate_Fwy.html|title=Original freeway plans for Washington, DC|access-date=October 6, 2014}}</ref>It also would've been the only auxiliary route of I-66.
