In what year did the Highway that connects the major metropolitan areas of St. Louis, Louisville and Lexington in Kentucky, Charleston, West Virginia, and Richmond, Virginia open?
1975
Grayson, Kentucky
Grayson is a home rule-class city in and the county seat of Carter County, Kentucky, United States, in the state's northeastern region.
 The population was 4,217 at the 2010 census.
 Along with Carter County, the city is closely associated with the nearby Huntington-Ashland, WV-KY-OH Metropolitan Statistical Area being just 9 miles west of the M.S.A's western boundary.
 The city has grown in size substantially since the opening of Interstate 64 in 1975 through Carter County.
 Immediately afterwards, Grayson experienced several years of commercial sector growth to serve the Interstate 64 traffic.
 Since 1990, the city has also seen significant growth in the residential sector with the Interstate making for a faster trip to and from Ashland.
 Beginning in 1995, AA Highway terminates in Grayson making the city a gateway to the Huntington-Ashland urban area.

 US 250 is the main east–west highway of Highland County, which is known as Virginia's Little Switzerland; the highway follows the path of the 19th century Staunton and Parkersburg Turnpike.
 From Staunton east to Richmond, the U.S. Highway serves as the local complement to Interstate 64 (I-64), roughly following the 18th century Three Notch'd Road through Waynesboro and Charlottesville on its way through the Shenandoah Valley, its crossing of the Blue Ridge Mountains at Rockfish Gap, and the Piedmont.
 In the Richmond metropolitan area, US 250 is known as Broad Street, a major thoroughfare through the city's West End and downtown areas. Tudor's Biscuit World
Tudor's Biscuit World is a restaurant chain based in Huntington, West Virginia, most commonly found in West Virginia.
 Many West Virginia locations share a building with Gino's Pizza and Spaghetti, although the chain is more extensive than Gino's (which is exclusive to West Virginia), having locations in southern Ohio, eastern Kentucky, and southwestern Virginia.
 In 2016 a franchise was opened in Panama City, Florida.
 Tudor's serves biscuits, biscuit sandwiches, homestyle breakfasts and dinners, muffins, and several side dishes.
 The chain was originally based in Charleston, West Virginia and many of the biscuit sandwiches are named for sports teams of interest in that area, including teams at Marshall University, West Virginia University, and The University of Charleston. Charleston, West Virginia metropolitan area
The Charleston Metropolitan Statistical Area, as defined by the United States Census Bureau, is an area consisting of three counties in West Virginia, anchored by the city of Charleston.
 It is the largest metropolitan area entirely within the state of West Virginia.

 The Interstate Highway is the primary connection between the Richmond–Petersburg metropolitan area and the Research Triangle and other major metropolitan areas of North Carolina.
 Like all mainline Interstate Highways, I-85 is a part of the National Highway System for its entire length in Virginia. Interstate 79
Interstate 79 (abbreviated I-79) is an Interstate Highway in the eastern United States, designated from Interstate 77 in Charleston, West Virginia to Pennsylvania Route 5 and Pennsylvania Route 290 in Erie, Pennsylvania.

 The highway connects the independent city of Harrisonburg (which also serves as the seat of Rockingham County), the town of Elkton, and an entrance to Shenandoah National Park.
 East of the Blue Ridge Mountains, US 33 connects the Piedmont communities of Stanardsville, Gordonsville, and Louisa.
 The U.S. Highway is a major suburban and urban route in the Richmond metropolitan area.
 Within Richmond, US 33 runs concurrently with US 250.

Interstate 85 (I-85) is a major Interstate Highway in the Southeastern United States.
 Its current southern terminus is at an interchange with I-65 in Montgomery, Alabama; its northern terminus interchanges with I-95 in Petersburg, Virginia, near Richmond.
 It is nominally north–south, but physically mostly northeast–southwest.
 While most interstates that end in a "5" are cross-country routes, I-85 is mainly a regional route, serving five southeastern states.
 Major metropolitan areas served by I-85 include the Greater Richmond Region in Virginia, the Research Triangle, Piedmont Triad, and Metrolina regions of North Carolina, Upstate South Carolina, the Atlanta metropolitan area in Georgia, and the Montgomery metropolitan area in Alabama
