Route description

Cabot to Austin

Highway 321 begins near an interchange with I-57/US 67/US 167 at Highway 5 and Highway 367 in Cabot. The route intersects Highway 89 in south Cabot before exiting the city and running due east. Near Oak Grove, the route turns due north, with Highway 321 Spur (AR 321S) continuing east to Highway 31. A 2010 study of annual average daily traffic (AADT) by the Arkansas State Highway and Transportation Department (AHTD) reveals that about 19,000 vehicles per day (VPD) use the route between its southern terminus and Highway 89/Highway 367, with the traffic count dropping to 7,000 VPD between that junction and the Cabot city limits. Traffic counts continue around 2,500 VPD until the Highway 321S junction, then drop to 2,100 VPD for the remainder of the route.

Beebe to Essex

Highway 321 begins north of Beebe at Highway 31. The route runs north, having a junction with Highway 321 Spur and passing through Essex. The highway continues north and terminates at Highway 267. An AHTD traffic count from 2010 reveals that the average annual daily traffic never exceeds 640 vehicles per day anywhere on the route.
