State trooper blends himself into the trees on the side of the road sideways to view the approaching traffic coming from the top of Blackwell hill going North. There is a construction zone that starts approx. 3 miles before mp 39 that is a 55 mph zone. As you go by Blackwell Rd. it stops construction zone and is back to 65mph until you get towards the top of the hill when it again turns back into a 55 construction zone going down the hill. Most/ all traffic is accelerating back up to normal speed when Mr. Stater has locked you on laser less than 1/2 mile (a few blocks within view) from mp 39.5 where it says "end Construction zone".
Beware of unmarked Troopers on the South end as well….SLOW DOWN TO 55 MPH and save yourself $200+ bucks!
