U.S. Highway 25

U.S. Highway 25 is a north-south US highway in the eastern United States of America that now connects Cincinnati, Ohio at the Ohio River to Brunswick, Georgia near the Atlantic Ocean. South of Cincinnati, US 25 is intact as a designation. In Kentucky it passes through Covington, Lexington, Kentucky, and Richmond and entering the Appalachians. At Corbin, it splits into US 25W and US 25E , and the highway 'unsplits' in Newport, Tennessee. The more westerly US 25W passes through Knoxville, Tennessee; the more easterly US 25E passes underneath Cumberland Gap via the Cumberland Gap Tunnel.

US 25 then passes southeastward into western North Carolina, passing through Asheville and then becomes an almost due north-south route between the Asheville and its terminus in Brunswick, Georgia through Greenville, South Carolina and Augusta, Georgia.

Former sections of US 25

US 25 originally extended northward into Ohio and Michigan before Interstate 75 between Detroit and Cincinnati and Interstate 94 between Detroit and Port Huron, Michigan made most of US 25 superfluous north of Cincinnati. In Michigan, Michigan 25 continues as the designation of old US 25 between Port Austin and Port Huron. Some old maps disagree on whether the east-west segment of what is now Michigan 25 between Bay City was US-25 or Michigan 25; for that discussion see Michigan State Highway 25.

Relics of US 25 between Brownstown Township, Michigan (a suburb of Detroit) and Cygnet, Ohio include U.S. Highway 24, Michigan State Highway 125, and Ohio State Highway 25.

US 25 in Michigan and Ohio was historically known as Dixie Highway, and the road is still so named in some places.

Related routes

US 25 has never had any "child" routes. Interstate 75, Interstate 40, and Interstate 26 in turn lie close to either US 25 or US 25W between Covington, Kentucky and Hendersonville, North Carolina. Only because Kentucky, Tennessee, and North Carolina are not as swift as Michigan and Ohio to decommission US routes that Interstate highways largely supplant does US 25 have much of its remaining length.

United States Highway 425 has no connection whatsoever to US-25, lying in Arkansas and Louisiana far to the west of any part of US-25, and is a major violation of the normal numbering system of the US highway system.
