Atually, once you get west of Berryville, it will start getting curvey and hilly all the way to Gateway. If traveling west, I would take 412 at Harrison and continue on to Siloam Springs. Depending on when you are traveling, Eureka Springs has become a motorcycle hot spot, it can be very trying with all of the stop and go, darting in and out of parking lots, and the snail's pace that can be experienced traveling through.
