On the NN side there isnt anywhere for them to hide ( i dont believe), but when you get to the Hampton side, there is a split where the a baracade is missing so they can sit facing either way and pull out after you. That split is about a half to a 1/4 mile from the hampton roads center parkways exit (right by the AMC for those who dont know that exit by name ).

edit: I got pulled by one sitting in the center when i was on my bike. I should have just ran away, but im a good boy, i wasnt doing too much over the speed limit.
