Two days each month, Allen police set up a speed trap near the Bridgewater Crossing neighborhood. There are two places they sit. During the day, they wait on the corner of Bridgewater and Ridgeview because the speed limit on Ridgeview is 30 but most people drive 45. During the night, they sit on the “bridge”” facing toward the light to catch people coming down the road who haven’t seen the speed limit sign yet. Quite a pricy ticket and here’s the catch: they only appear two days out of each month.”
