ADVANCE FOR MONDAY MAY 26 AND THEREAFTER - In this May 21, 2014 photo, a speed limit sign posts a 55 miles per hour speed limit for traffic on State Highway 13 in Burnsville, Minn. Lawmakers have urged transportation officials to boost the speed limit to 60 mph where it can "reasonably and safely" be done on two lane-two way state highways now covered by a 55 mph limit.
