Watch out for unmarked Detroit traffic cops and State Police sitting on the right shoulder of the freeway just after curves. Being that this freeway is sunk into the ground, when it curves there are blind corners created by the concrete retaining walls. The speed limit is 55mph, but speeds are usually between 65-85mph. Also keep an eye out for the State Trooper on the entrance ramp of McNichols Rd. if you are heading south on M-10.
