During high traffic flow times, Mornings and weekends, Police will run radar just past the Davidson rd. exit on I-29 South. At the Davidson rd. entrance ramp to I-29S the interstate narrows to one lane from the left and also one lane from the right creating a bottleneck. Driver’s trying to enter the interstate from the Davidson Rd. entrance ramp at posted speeds of 55 mph are forced to try to blend into a heavy traffic load of drivers trying to merge suddenly from the left due to poor signage warning of the merge into one lane. Someone has to speed up and the Police sit some 100 yards past the overpass which goes over I-29, behind the overpass bridge columns,just past where the Davidson rd./ I-29 South intersect and catch people speeding up to try to merge into this one lane. Usually Police Cars as well as Motorcycle Officers.
