The route then intersects another route of AR 185 by the Helena Country Club and then intersects US 49 (Martin Luther King Jr. Drive[4]), a four-lane divided highway, at an at-grade intersection in the south part of the city. The highway then turns to the southwest and reaches its eastern terminus at AR 44.
Beginning from the end of the Highway 1 to the US 49B concurrency, the route is designated as part of the Mississippi River Trail, a 3000miles bike route from New Orleans to Minnesota along the Mississippi River.
