Oklahoma State Highway 128

State Highway 128 begins at US-59/US-270 in Heavener. From the terminus south of downtown, the highway follows West Avenue I to East 1st Street, where it turns south, running parallel to US-59/US-270. Highway 128 then curves east and exits Heavener.[2] For the remainder of its route, SH-128 runs mostly parallel to a spur from the Kansas City Southern rail line; the road crosses the tracks once, just east of the Heavener city limit.[3] SH-128 follows the valley of the Poteau River through east-central Le Flore County, running between the river and Poteau Mountain. At the highway's approximate midpoint, the route passes through unincorporated Forrester. From here, SH-128 follows a generally east-northeast heading before crossing the state line into Scott County, Arkansas. The road continues east toward Bates as Arkansas Highway 28.[4]

State Highway 128 first appears on the 1957 edition of the official Oklahoma state highway map. The route has always been a paved highway. Initially, it did not connect to Highway 28 upon crossing the Arkansas state line.[5] The route was realigned to directly connect to Highway 28 by 1961.[6] No further changes have occurred to the highway since that time.
