Seattle, Washington Speed Traps
Interstate 520 evergreen floating bridge, mid span
State patrol cruiser parked mid span in the "service cut out". Hidden location, usually late (typically after 11 pm) when traffice is light. Speed limit is posted 50 mph, and of course, the prevailing speed is around 60-65. I have gone by at 65 several times and never been stopped. They must be hitting those going over 70 mph. I have seen them work both directions, but they seem to favor the westbound lanes.
I-5 I-90 or any main highway
Higway Patrol has wolf packs and will pull over as many cars as they can do not speed in that state.
Airport Way S
A classic speed trap. Northbound on Airport way the limit drops for no reason from 35 to 30 so that all those folks going 5 over are suddenly 10 over. Note, the speed limit on the other side of the street is still 35! Seattle Police like to hide in the Brewery parking lot to snag the unwary.
Highland Park way hill
This is the old Boeing hill in the Highland Park area of Seattle. There are two SPD Bike officers that sit about mid way down the hill on the first street to your right. Speed limit is 30. Even with breaks on it is very hard to go under 40 on that steep of a hill. They pull all speeders over in the next driveway.
3rd Av. NW, between N. 110th and N. 115th
At the bottom of a big dip on 3rd, one or two motorcycle officers sit by the side of the road. They wait for cars that speed up coming down the fairly steep hills both ways. It is easy to get caught if you don’t use your brakes coming down hill (limit: 30mph). Times of trap use vary.
