North and South Bound Rte 95. From exit 48 to exits 58 or so. THis entire stretch o fhighway is patrolled in the extreme. They use marked and unmarked(cars and trucks etc) cars here. I travel this road every day and see several people pulled over at all hours of the day. Be very wary. They are often under the many bridges, or on the ramps. There is a State police barracks off of exit 56.
