Cle Elum, Washington Speed Traps
Heading east out of town the speed limit slowly increases from 45 to 55 and then to 60 at about mile marker 5. Police patrol fairly heavily vehicles entering this slow down from the west (mile marker 5) or sit on the side of the road near Airport Road to get folks speeding up too early for the 60 MPH stetch or who failed to slow down in the 55 MPH stretch. Both State Police and Kittitas County Sheriffs deputies can be found on this stretch of road.
At mile post 62 East bound on I-90, the speed limit decreases to 65 from 70, rather abruptly, on a down grade. State Patrol officers are camping out on the center median.
The Upper Kittatas County District Court is not interested in hearing mitigation either, so be cool on this stretch. You will still get to Spokane on time.
I test cars for a living and travel often along this stretch. It’s quite common to see police lurking around the corners with radar in hand. Note that through Snoqualmie the speed drops to 65 and jumps back to 70 MPH immediately after the speed trap (mile 65.5).
WSP will usually sit just over a hill rise or around a corner and triger you with lazer, giving your detector no time to warn you. The WSP there use numerous vehicles, from motorcycles to suburbans.
