U.S. Route 127 (US 127) is a 758adj=midNaNadj=mid north–south U.S. Highway in the eastern half of the United States. The southern terminus of the route is at US 27 in Chattanooga, Tennessee. The northern terminus is at Interstate 75 (I-75) near Grayling, Michigan. Since 1987, it has been the core of the annual World's Longest Yard Sale, also known as the Highway 127 Corridor Sale (127 Yard Sale), which now stretches 690miles from Addison, Michigan, to Gadsden, Alabama. The sale, held every August, was started to demonstrate that the older U.S. Highway System has something to offer that the Interstate Highway System does not.[1] In Michigan, US 127 tripled in length in 2002, taking mileage from its parent, US 27.

See main article: U.S. Route 127 in Tennessee. In Tennessee, US 127 traverses rural areas of the Cumberland Plateau in eastern Middle Tennessee and western East Tennessee. The route officially begins in the northern Chattanooga suburb of Red Bank at an interchange with US 27, where it overlaps Tennessee State Route 8. From there it runs primarily northwest as it passes Signal Mountain, and later Walden Ridge before entering Dunlap, where it turns northeast along Tennessee State Route 28. After TN 8 leaves at the interchange with TN 111, US 127/TN 28 follows through the Sequatchie Valley, passing through the city of Pikeville, then curves back to the northwest as it enters Crossville, only to return towards the northeast as it enters Jamestown. From that point on it returns towards the northwest one more time as it winds through the woods surrounding the Sgt. Alvin C. York State Historic Park. Finally in Static, the road runs along the Tennessee-Kentucky border where it makes a sharp turn at the northern terminus of TN 111 before entering Kentucky.
See main article: U.S. Route 127 in Kentucky. In Kentucky, US 127 is cosigned with US 42 through Cincinnati's Northern Kentucky suburbs until 5miles east of Warsaw, then passes south through Owenton. This was the road driven by Buddy Rich when he wrote "Blue Grass makes me Blue" in 1947.[2] At the state capital of Frankfort, it becomes a four-lane highway, then skirts Lawrenceburg, Harrodsburg, and Danville. It enters the hilly Knobs Region at Junction City, where it becomes a two-lane route, and continues through Hustonville, crossing the drainage divide between the Kentucky and Green river watersheds and roughly following the scenic upper Green River valley through Casey County, crossing the river at Liberty. South of Dunnville it climbs onto the Eastern Pennyroyal Plateau and cuts through Russell Springs and Jamestown. It crosses Wolf Creek Dam, which creates Lake Cumberland. It runs very briefly with KY 90 north of Albany and crosses into Tennessee at Static. The new route through Clinton County includes a bypass west of Albany; the original plan for a more direct eastern route was abandoned because of historic and scenic concerns. In the county US 127 runs through sinkhole plains along the escarpment that marks the western edge of the Cumberland Plateau, creating scenic views.
See main article: U.S. Route 127 in Ohio. US 127 serves several cities and rural communities along the extreme western edge of Ohio, including Cincinnati, New Miami, Seven Mile, Somerville, Camden, Eaton, Greenville, Celina, Van Wert, Paulding and Bryan. In Cincinnati, it shares a short concurrency with its parent route, US 27, along with US 42. From there, it heads north through Fairfield and Hamilton. The highway is a four-lane, divided bypass around Greenville. US 127 crosses the Ohio Turnpike near West Unity, but does not intersect with it. It also joins with US 36 for about 5miles. The first city US 127 enters after leaving Kentucky is Cincinnati. The last municipality that US 127 goes through before reaching Michigan is West Unity.
Except for Defiance County, US 127 passes through the county seats of all nine counties in Ohio that share a border with Indiana. It also traverses a portion of Fulton County before entering Michigan.
In total, US 127 traverses 194.2miles across Ohio.
See main article: U.S. Route 127 in Michigan. In Michigan, US 127 runs from the Ohio border south of Hudson north to the junction with I-75, 4miles south of Grayling, a distance of .[3] [4]
The highway is the primary route connecting Lansing and central Michigan to Northern Michigan and the Mackinac Bridge; it serves the cities of Jackson, Lansing, and Clare. From the south side of Jackson northerly, it is mostly a four-lane freeway, except for the notable exception of a 160NaN0 stretch from north of St. Johns to just south of Ithaca, where access to the road is not limited.
Prior to 2002, US 127 ran from I-69 north of East Lansing southerly to the Ohio border near Hudson, a total of .[5] [6] From the Ohio border until Jackson, the highway follows the course (with minor deviations) of the Michigan Meridian used to survey Michigan in the early 19th century. That stretch is generally named Meridian Road.[7] In the non-freeway sections of the route, it is known as Bagley Road.
A proposed I-73 would incorporate US 127 between Jackson and Grayling.[8] However, Michigan abandoned plans for building I-73 in 2001.
US 127 originally terminated at Toledo when it was commissioned in 1926. At that time, the southern portion ran from Somerset to Toledo along the route of present-day U.S. Route 223. In 1930 the southern terminus moved to Cincinnati, and in 1958 it was extended to its present southern terminus at Chattanooga.[9]
The northern terminus of US 127 was in or near Lansing, Michigan, from its inception in 1926 to 2002. In 2002, the terminus was moved to an intersection with I-75 south of Grayling in Crawford County, Michigan, replacing all of US 27 north of Lansing.[5] [6]
