The Camden to Washington Road-Rosston Segment is a historic early 19th-century road section in rural Nevada County, Arkansas. It is located east of Rosston in Poison Spring State Forest, and is a former portion of County Road 10 extending east from that road's junction with County Road 47 (Kirk Road). The road was first cut , and was never paved or given modern finishing, despite its continued use well into the 20th century. A crossing at Cypress Creek has been compromised by the activities of beavers, and the road is no longer completely passable, possibly excepting high-clearance off-road vehicles. The road section is one of the only sections of the historic post road which connected Washington and Camden to retain its 19th-century character.
The road section was listed on the National Register of Historic Places in 2009. The Carolina Methodist Church is located on this section of road.
