U.S. Highway 23 Business
Location	Cochran, Georgia
Length	4.1 mi[9] (6.6 km)

U.S. Highway 23 Business (US 23 Bus.) is an at least 4.1-mile (6.6 km) route that goes through downtown Cochran, Georgia. It is entirely concurrent with SR 87 Bus.

US 23 Bus./SR 87 Bus. begins at an intersection south of Cochran and travels to the northwest. The highway crosses a railroad bridge over a Southern Railway line and becomes Southeast Second Street, traveling through the grounds of the Middle Georgia State University Cochran Campus. After leaving the vicinity of the campus, it eventually intersects SR 26 (Dykes Street), and Southeast Second Street not only becomes Northeast Second Street but is also shared in a concurrency with US 129 Alternate (US 129 Alt.) and SR 112. The vicinity is also the site of the National Register of Historic Places (NRHP)-listed Cochran Municipal Building and School and the Bleckley County Courthouse. Between East Ash Street and East Railroad Avenue, the highway curves to the northeast with that same Southern Railway line earlier flanking the west side, although the tracks begin to move away from the road north of unmarked Emergency Route 105.^{[citation needed]} The business route ends at US 23/SR 87, but US 129 Alt. joins the route in a concurrency into Macon, while SR 112 travels concurrently only as far as north into Royal along the same concurrency until branching off toward Milledgeville.

U.S. Route 23 Business
Location	Big Stone Gap–Norton, Virginia
Length	16.0 mi[19] (25.7 km)
Tourist routes	Virginia Byway

U.S. Route 23 Business (US 23 Bus.) is a 16-mile (26 km) business route of US 23 between Big Stone Gap and Norton, Virginia.

US 23 Bus. begins in Big Stone Gap at an interchange along mainline US 23 with US 58 Alt. and State Route 844 (SR 844), the former of which joins US 23 in an overlap until it reaches Norton northbound US 23 Bus. and westbound US 58 Alt. wind around Gilley Avenue East until it reaches East 5th Street South, then turns north. At Wood Avenue East (SR 610), US 58 Alt. turns west, ending the concurrency, and the name changes to East 5th Street North. The route crosses a bridge over the Powell River then after passing a local car dealership across from East 5th Avenue becomes Roaring Branch Road. Most of this mountainous road winds around the Powell River, Norfolk Southern Railway's Appalachia District, and an abandoned Louisville and Nashville Railroad line currently in the process of being converted into a rail trail. The route turns more towards the east as it enters Appalachia, where it is renamed West Main Street, and serves as the eastern terminus for SR 68. The road name is changed to East Main Street after the southern terminus of SR 78 a bridge over Norfolk Southern Railway's Clinch Valley Extension, and then follows the rest of the line east. Leaving town, the road is named Kent Junction Road, and at SR 603 where it passes a bridge over the junction the road was named for which also contains the Paradise Branch. The street name still remains after passing this junction, and, along the way, it passes the Central Drive-In Theatre just before passing through Blackwood.

Descending from the mountains, the area becomes slightly more developed as it passes by the NRHP-listed Country Cabin community center, and through a forgotten unincorporated community named Josephine. East of SR 621, the route officially enters Norton, and the street is named Park Avenue Northwest. Within downtown Norton, the road encounters US 58 Alt. Bus. at 11th Street Southwest and is joined by that route in an overlap. Continuing to run straight east through the city, it encounters the western terminus of SR 74 at Coeburn Avenue Southwest, which runs southeast of the routes. East of SR 74, the routes climb an embankment and becomes a divided highway, though the US 23 Bus./US 58 Alt. Bus. overlap is about to come to an end. Just before the interchange with mainline US 23, US 58 Alt. Bus. continues east straight ahead along unmarked SR 283 (Norton Coeburn Road) while US 23 and Park Avenue Northeast make a sharp turn to the north. From this point on, the route is a two-lane highway with a continuous center left-turn lane, winding around the west side of the Guest River, and Norfolk Southern Railway's Glamorgan Branch. Snaking closer to the railroad and the river, it leaves the Norton city limits at the intersection with SR 620 and the Glamorgan Branch at the same time, just before crossing a bridge over the Guest River where the street is named Esserville Road. US 23 Bus. ends at the intersection of US 23 across from SR 757 (Wise–Norton Road).
