Connecticut Avenue is a major thoroughfare in the Northwest quadrant of Washington, D.C., and suburban Montgomery County, Maryland. It is one of the diagonal avenues radiating from the White House, and the segment south of Florida Avenue was one of the original streets in Pierre (Peter) Charles L'Enfant's plan for Washington. A five-mile segment north of Rock Creek was built in the 1890s by a real-estate developer.
