Arkansas Highway 155

Highway 155 in Mount Nebo State Park

The route begins at Sunset Point on the north rim of Mount Nebo, in its respective state park, Mount Nebo State Park. It is surrounded by a dense forest while on the mountain and passes near the historic Mt. Nebo State Park Pavilion, the visitor center, and other points of interest in the park. Highway 155 winds down the mountain on eleven hairpin curves with very steep grades, as much as 18% in places. There are no alternative routes, as Route 155 is the only road up or down the mountain. As a result, the route is a popular destination for motorcycle riders, and trailers or RVs over 24 feet are prohibited in the state park.[5] It eventually points due east toward Dardanelle. The route intersects with Highway 22 in the city and terminates.

The route begins at Arkansas Highway 7 and runs east and south[a 1] through Old Neely to Arkansas Highway 154 in a right-angle manner. The route does not cross or concur with any other state highways. The route essentially serves as giving Old Neely access to the state highway system.

Highway 155 runs south from Petit Jean State Park

The route begins at Arkansas Highway 10 just east of Casa and runs north to serve as a terminus for Highway 247 and Highway 324. AR 155 continues to wind through forests before terminating at Highway 154 in Petit Jean State Park near the historic Seven Hollows Site.

Arkansas Highway 155 is a brief spur route that begins at Arkansas Highway 60. The route runs due south[a 2] to terminate near Deberrie, which is an unincorporated community.[4]
