Arkansas Highway 174 (AR 174, Ark. 174, and Hwy. 174) is a designation for a state highway in Southwest Arkansas. The route is split into two sections. The first section begins at AR 355 in Spring Hill and ends at US Route 67 (US 67) in Hope. The second section begins at US 67 in Perrytown and ends at AR 299 just south of Interstate 30 (I-30).[1] AR 174 is one of the few exceptions to the rule of an even-numbered state highway traveling north to south, rather than east to west.
