Old US 71 – Wilton Segment is a former alignment of U.S. Route 71 (US 71) near Wilton in Little River County, Arkansas. The roadway of about 2 miles (3.2 km) is a 1934 construction and was the main travel route in the county upon construction until US 59/US 71 bypassed this alignment in 1965.
Old US 79, Kingsland Segment is a rare drivable section of concrete highway built in 1938 near Kingsland, Arkansas. It is also one of a few surviving sections of the original alignment of U.S. Route 79 (U.S. 79) in Arkansas. The road that became US 79 had been laid out by 1916, and was paved with asphalt in 1930. In the mid 1930s, the state embarked on a program of removing dangerous grade crossings where major routes crossed railroad tracks. In 1938, it awarded a contract to S. M. Dixon to build an overpass at the crossing of US 79 and the St. Louis Southwestern Railway line. Dixon built a 655-metre-long (2,149 ft) section of concrete roadway, 22 feet (6.7 m) wide, with a concrete deck girder bridge to cross the tracks. This section of US 79 remained in service until 1954, when the current alignment to its northeast was built. It has since been designated County Road 22. The concrete is in good condition; it has been covered in chip seal for about half its length.
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. The road was first cut c. 1825, 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 the one of the only sections of the historic post road which connected Washington and Camden to retain its 19th-century character.

The roadway portion, in parts set in dramatically deep cuts in the hills, extends from Village Creek in the east to the western boundary of the park, and is accessible today as a hiking trail.
