The speed limit on this road between 50 st and rollyview road is ridiculous. It's a major four lane arterial road with no driveways backing onto it and pedestrian crossings fully signalized yet the speed limit is only 50 km/h. Why ?. Both sparrow drive and 47 st have many more accesses on them yet the speed limit is higher. Doesn't make any sense.
