The ArDOT maintains AR 355 like all other parts of the state highway system. As a part of these responsibilities, the Department tracks the volume of traffic using its roads in surveys using a metric called average annual daily traffic (AADT). ArDOT estimates the traffic level for a segment of roadway for any average day of the year in these surveys. As of 2022, AADT ranged from 2,800 VPD in Fulton, 2,400 VPD near Saratoga, and 2,700 VPD near Mineral Springs, but dropped to 520 VPD and 320 VPD on the north and south sides of the US 371 intersection, respectively. The second segment had an AADT of 520 VPD. The third segment had the lowest counts, with 290 VPD near Patmos, 300 VPD near Falcon, and 460 VPD near the eastern terminus.[6] For reference, the American Association of State Highway and Transportation Officials (AASHTO), classifies roads with fewer than 400 vehicles per day as a very low volume local road.[7]
No segment of Highway 355 has been listed as part of the National Highway System,[8] a network of roads important to the nation's economy, defense, and mobility.[9]
Shortly upon entering Howard County, AR 355 serves as the eastern terminus of AR 32 at Saratoga (a census-designated place) near the Saratoga Blackland Prairie Natural Area. The route continues north along the east side of Lake Millwood before entering the small town of Tollette. Within Tollette, AR 355 is known as Martin Luther King Jr Road, passing Tollette City Hall before serving as the western terminus of AR 332 (Schooley Road).[12] Continuing north, AR 355 winds to Mineral Springs, where it overlaps AR 27 through downtown before turning north alone and winding into a rural part of Howard County. AR 355 intersects US 371 approximately 4 miles (6.4 km) west of Nashville before winding north to a junction with US 278, where it terminates.[13]
Spring Hill to Evening Shade
A second section of AR 355 begins in Columbia County approximately 6 miles (9.7 km) southwest of Hope and 4 miles (6.4 km) east of Bois D'Arc Creek Wildlife Management Area (WMA). The designation begins at an intersection at the unincorporated community of Spring Hill near Spring Hill High School, with AR 174 running north and a county road (Spring Lake Road) continuing south from the junction. AR 355 runs southeast to a junction with AR 29 at Evening Shade, where it terminates.[11] The roadway continues east as Hempstead County Route 8 (CR 8, HP Powell Road).
Highway 55 was one of the original state highways, designating a gravel road between Fulton and Mineral Springs as State Road 55.[1] By the 1953 state highway map, a second segment was created between Spring Hill and Evening Shade.[16][17] The route was realigned around Mineral Springs and through Tollette in 1955.[18] On March 7, 1962, the Highway Commission extended AR 355 from Mineral Springs to the current northern terminus (AR 4, now US 278).[19]
The Arkansas General Assembly passed the Act 148 of 1957, the Milum Road Act, creating 10–12 miles (16–19 km) of new state highways in each county.[20] Following the act, two additional segments of AR 355 were created on July 10, 1957: from AR 29 to Patmos,[21] and from Willisville to AR 53.[22] In 1958, all segments were re-numbered to avoid duplication following the designation of I-55 in the state.[23] The third segment was extended east from Patmos to the Nevada County line on April 24, 1963 as part of a large addition of county roads to the state highway system,[24] with another extension to Falcon on November 23, 1966.[25] On January 26, 1977, the Highway Commission approved a designation swap in Nevada County to improve route continuity: AR 355 between Bodcaw and Willisville became AR 32, with the segment of AR 32 from Falcon to the Columbia County line becoming AR 355.[26] On June 29, 1978, the Columbia County judge requested an extension of AR 355 east to AR 19 at Lamartine (now US 371).[27]
On February 18, 1959, the Arkansas State Highway Commission agreed to a proposal from the Hempstead County judge to return AR 355 between Spring Hill and Evening Shade, and portions of AR 32, to county maintenance in exchange for extending AR 29 from Blevins to AR 19.[28] The former AR 355 alignment was restored to the state highway system on November 23, 1966, including an extension to Bois D'Arc Lake, as part of a large addition of county roads to the state highway system.[29] The following year, the alignment was switched to follow a different series of county roads at the request of the Hempstead County judge, having previously followed CR 63 and CR 163.[30]
