United States Highway 1

United States Highway 1 parallels the east coast of the United States; it runs 2390 miles from Key West, Florida in the south to Fort Kent, Maine at the Canadian border in the north. It parallels Interstate 95, although for a longer route and usually further to the east. It connects the major cities of the east coast, including: Miami, Florida, Jacksonville, Florida, Augusta, Georgia, Columbia, South Carolina, Raleigh, North Carolina, Richmond, Virginia, Washington, D.C, Baltimore, Maryland, Philadelphia, Pennsylvania, Trenton, New Jersey, Newark, New Jersey, New York City, and Boston, Massachusetts.

It is labeled "US 1" because it is the US Federal Highway furthest east, and the north-south highways are numbered east to west.

The section from Savannah, Georgia to Miami, Florida in most places closely follows the old route of the earlier Dixie Highway.

One of Andy Griffith's first successes as an entertainer was a comic monologue called "Number One Street", which told the tale of a rural family experiencing the wonders of the highway: "There was a sign said 'Free Picnic Table', so naturally we stopped and got us one."
