Des Peres, Missouri Speed Traps
Interstate 270 near Manchester/Dougherty Ferry Road
Radar and airplane tracking most commen. Local Police or State Highway Patrol alternate coverage throughout the day. High enforcement towards the end of each month during non peak traffic periods. Police and patrol officers on shoulder at top of on ramps for both north and south bound traffic.
Manchester Road west of I-270 to the white castle
Beware, MHP and des peres police watch this area good. Speed limit is 45 mph, but those familiar with the area know that some do as much as 65, since the road has no stoplights or intersections until the EB and WB lanes come together again at the white castle. I have done 50 with no problems, main point to watch for is the U-turn lane just west of the big southwest bank bldg.
