Directly beneath the 236th st overpass, just after exit 178 going northbound in the median between a wall on the left side and the supports of the overpass, and going southbound on the left side of the road behind the overpass at exit 177, I see a WSP trooper hanging out often. He checks both directions and it’s a great vantage point to get northbounders, as usual, you can’t see him till you’re within 50ft of his car. I see northbound enforced during the middle of the day and southbound at night.
