Exceptionally wide median just after bridge over Western Run–two marked MSP cruisers pulled well off into shrubbery in the median. Police shoot laser at southbound traffic approaching down a long 1/4 mile hill. I was stopped for 83 mph in a 65, which was not much faster than prevalent traffic speed given the undeveloped area and aforementioned long hill. I was directed to back up on the left shoulder so my white car would not be as visible to future victims. Two officers were working, and they stopped three more cars in the 10 minutes I spent on the side of the road. As soon as the other officer was done with a vehicle, he would stop the VERY NEXT ONE coming down the hill. Not sure the mile marker, but be vigilent on I-83 southbound when you are less than 10 miles out from the I-695 interchange.
