United States Numbered Highways in the U.S. state of Connecticut, are numbered by the American Association of State Highway and Transportation Officials (AASHTO) and maintained by the Connecticut Department of Transportation, a total of 547.75 miles (881.52 km) as a system of state highways and are numbered from 1 to 202.

History

In 1926, the U.S. highway system was implemented. U.S. Routes 1, 5, 6, and 7, plus 202 were used as designations on several primary state highways, replacing New England routes 1, 2, 3, and 4, respectively. The other New England routes that were not re-designated as U.S. routes became ordinary state highways but kept their number designation, which are used even today (with some realignment).
