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.
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).
North Carolina Highway 42 (NC 42) is a 223 mi state highway and a semi-urban traffic artery connecting Asheboro, Sanford, Clayton, Wilson and Ahoskie as well as many small to medium-sized towns throughout Central and Eastern North Carolina.
 The highway is primarily rural, avoiding larger cities such as Raleigh.
 NC 42 begins at Interstate 73 (I-73)/I-74/US Highway 220 (US 220) on the western side of Asheboro.
 From there the highway runs southeast toward Sanford.
 Running through the heart of Sanford, NC 42 intersects several major highways such as US 1 and US 421.
 Leaving Sanford the highway runs along the southern side of the Triangle Area, while servicing the smaller towns of Fuquay-Varina and Clayton.
 Further east the highway intersects both I-95 and US 264, shortly before entering into central Wilson.
 Leaving Wilson the highway continues to the northeast, and intersects US 258 near Crisp.
 North of intersecting US 64, NC 42 begins a concurrency with NC 11 from Hassell to western Ahoskie.
 Nearing Ahoskie the highway turns to the east and runs south of the center of the town.
 NC 42 follows concurrently with US 13 southeast to Powellville.
 Nearing its eastern terminus the highway turns east along its own routing until reaching NC 45 in Colerain where the highway ends.
There are three business routes of US Highway 10 in the state of Michigan.
 They serve as connections from the main highway into Reed City, Clare and Midland.
 Additionally, there were another two business routes that connected US Highway 10 (US 10) to the downtowns of Flint and Pontiac.
 All of these business routes are, or were, former sections of US 10 that were marked Business US Highway 10 (Bus.
 US 10) after the main highway was realigned to bypass the downtowns of the cities.
