Arkansas Highway 25

Arkansas State Highway 25 is a diagonal northeast-southwest highway in central and northeastern Arkansas between Conway, Arkansas (junction US 64) and Black Rock, Arkansas (junctions US 63, U.S. Highway 412, and Arkansas State Highway 166. Near Conway it is strictly a local route not significant enough to have access to Interstate 40; meeting U.S. Highway 65 at Greenbriar, it then takes a course through Heber Springs and Batesville through the foothills of the Ozarks. Except where it coincides with US 65 near Greenbriar it is entirely undivided surface highway. This hilly, curvy road is scenic in places, but it is not recommended for those pressed for time. It is useful for those seeking the recreational areas along it. U.S. Highways 64 and 67 form, by Arkansas standards, a faster (if bland) alternative for its entire course.

Before 1982 it included an east-west highway between U.S. Highway 63 approximately 2 miles southeast of Portia, Arkansas and the Missouri State Line, where it continued as Missouri State Highway 25. In 1982 this road was redesignated as the anomalous U.S. Highway 412. Major towns along this road include Walnut Ridge and Paragould, Arkansas. This flat, largely straight section through cotton country was in no way scenic.
