When going towards the 610 bridge where theres and exit onto noble slow down! every once in awhile a line of up to 8 police cars will be on the exit ramp on the other side ,unseen from the drivers until its to late, and another police officer will be ontop of the bridge with the laser checking every car. Once you see that cop if you are over 70mph ,the speed limit is 65, you are already busted my only advice is accept that your busted and drive on.
