There is a very difficult move to make a left-hand turn (no light, sort of a semi-jughandle)) on Rt. 202 southbound after exiting Rt. 80, to head towards Littleton Road. If you miss the turn you must go down a half-mile to make a U-turn. Police commonly stake out this area to catch people making illegal U-ies. This is a very busy road southbound in the morning (empty northbound), so many people try to turn to find a less-congested route. Much $$$ for the town – these guys are out there five days a week.
