Johnson is a samll town completely surrounded by Fayetteville/Springdale. Once a road crosses into Johnson, the speed limit falls by 5 – 10 mph and Johnson police are eager to get you on it any time of day. Beware especially of Wilkerson Ave. before it turns into Gregg Street in Fayetteville. The speed limit is 30 even though it’s a wide blvd. with 4 lanes and very little turning on/off traffic. Beware also of turning right onto Wilkerson from Joyce Street. I’ve often seen police cars waiting happily there for motorists who have forgotten to lower their speeds from the Fayetteville limits.
