RPD posts serveral police units on the ramp to the "Outer Beltline." When I merged onto I-40/440 toward the Benson exit, I witnessed no less than 5 cars that had been pulled over and two additional units that were still on the ramp, waiting for more speeders. Of course, it’s one’s own fault when getting caught for speeding, but perhaps knowing about this trap, some travelers will slow down.
