Question: Dorton, Kentucky is located along a US highway that runs between Jacksonville, Florida and what Michigan city?
Context: Dorton is an unincorporated community and coal town in southern Pike County, Kentucky, United States.  Located along U.S. Route 23, also known as Country Music Highway, it lies at 37.27667°N, 82.57917°W at an altitude of 683 feet.  It is centered at the confluence of Dorton and Shelby Creeks and the junction of U.S. 23 and KY 610, 13 miles south of Pikeville. US Highway 23 (US 23) is a United States Numbered Highway that runs from Jacksonville, Florida, to Mackinaw City, Michigan.  In the US state of Michigan, it is a major, 362 mi , north–south state trunkline highway that runs through the Lower Peninsula (LP).  The trunkline is a freeway from the Michigan–Ohio state line near Lambertville to the city of Standish, and it follows the Lake Huron shoreline from there to its northern terminus.  Serving the cities of Ann Arbor and Flint, US 23 acts as a freeway bypass of the Metro Detroit area.  Overall, the highway runs through rural areas of the state dominated by farm fields or woodlands; some segments are urban in character in the Ann Arbor, Flint and Tri-Cities areas.  The section from Flint north to Standish also carries Interstate 75 (I-75) along a concurrency that includes a segment that carries almost 70,000 vehicles on a daily basis. US Highway 12 (US 12) is an east–west US Highway that runs from Aberdeen, Washington, to Detroit, Michigan.  In Michigan it runs for 210 mi between New Buffalo and Detroit as a state trunkline highway and Pure Michigan Byway.  On its western end, the highway is mostly a two-lane road that runs through the southern tier of counties roughly parallel to the Indiana state line.  It forms part of the Niles Bypass, a four-lane expressway south of Niles in the southwestern part of the state, and it runs concurrently with the Interstate 94 (I-94) freeway around the south side of Ypsilanti in the southeastern.  In between Coldwater and the Ann Arbor area, the highway angles northeasterly and passes the Michigan International Speedway.  East of Ypsilanti, US 12 follows a divided highway routing on Michigan Avenue into Detroit, where it terminates at an intersection with Cass Avenue. Mississippi Highway 5 (MS 5) is a state highway in Benton County, Mississippi, United States.  It runs 26.929 mi from MS 178 in Hickory Flat north to U.S. Route 72 (US 72) to the south of Michigan City.  The route runs through the Holly Springs National Forest for much of its length and passes through Ashland.  To the south of Ashland, MS 5 has a concurrency with MS 4.  The MS 5 designation was first used by 1932 for an unpaved road between Hickory Flat and the Tennessee border in Michigan City.  In 1943, the northern terminus was cut back to US 72.  MS 5 was completely paved by 1951 and has retained its current alignment since then. U.S. Route 23 (US 23) is a long north–south U.S. Highway between Jacksonville, Florida, and Mackinaw City, Michigan.  It is an original 1926 route which originally reached only as far south as Portsmouth, Ohio, and has since been extended. Highway 5 (AR 5, Ark. 5, and Hwy.  5) is a designation for three state highways in Arkansas.  The southern segment of 44.99 mi runs from Highway 7 in Hot Springs north to US Highway 70 (US 70) in Little Rock.  A northern segment of 146.63 mi begins at US Highway 67/US Highway 167 in Cabot and runs north to Missouri Route 5, including a lengthy overlap with Highway 25 between Heber Springs and Wolf Bayou.  A portion of Highway 5 is designated as part of the Sylamore Scenic Byway. Haskell and Barker Historic District is a national historic district located at Michigan City, LaPorte County, Indiana.

US Highway 31 (US 31) is a part of the United States Numbered Highway System that runs from Alabama to the Lower Peninsula of the US state of Michigan.  In Michigan, it is a state trunkline highway that runs from the Indiana–Michigan state line at Bertrand Township north to its terminus at Interstate 75 (I-75) south of Mackinaw City.  Along its 356.5 mi route, US 31 follows the Michigan section of the St. Joseph Valley Parkway as well as other freeways and divided highways northward to Ludington.  North of there, the trunkline is a rural undivided highway through the Northern Michigan tourist destinations of Traverse City and Petoskey before terminating south of Mackinaw City.  Along its route, US 31 has been dedicated in memory of a few different organizations, and sections of it carry the Lake Michigan Circle Tour (LMCT) moniker.  Four bridges used by the highway have been recognized for their historic character as well. State Road 520 is a four-lane connector about 1,000 feet (305 m) in length.  It exists solely to connect U.S. Route 12 and U.S. Route 20 in Pines, about 3 miles (5 km) west of Michigan City.  U.S. 12 and U.S. 20 do not cross at this point — they parallel each other for another 22 miles (35 km) westbound and overlap in Gary; U.S. 20 is generally considered the faster of the two, while U.S. 12 is the scenic Dunes Highway.  Eastbound, U.S. 12 travels through Michigan City and northeast into Michigan where it forks east from the Red Arrow Highway.  U.S. 20 stays in Indiana and runs around Michigan City as a bypass to the south. There are currently eight business routes of Interstate 94 (I-94) in the US state of Michigan.  These business routes connect I-94 to the downtown business districts of neighboring cities.  These eight routes are all business loops which bear the Business Loop I-94 (BL I-94) designation.  These loops are former routings of I-94's two predecessors in Michigan: US Highway 12 (US 12) or US 25.  The westernmost BL I-94 runs through the twin cities of Benton Harbor and St. Joseph along the former routing of US 12 and US 31/US 33 that now includes a section of the Lake Michigan Circle Tour in the state.  The loops in Kalamazoo, Battle Creek, Marshall, Albion, and Jackson were also formerly segments of US 12 which were later designated as separate version of Business US Highway 12 (Bus.  US 12) through their respective cities before becoming BL I-94s in 1960.  The route of the business loop through Ann Arbor was previously US 12 and then later M-14 before receiving its current moniker.  The BL I-94 through Port Huron was previously US 25 and then Business US Highway 25 (Bus.  US 25).
