Duluth is well known for it’s police. It is still safe to go at least 10m.p.h. over the limit in any given area. You should take extra caution on Peachtree Industrial Blvd. NB before Rogers Bridge Road( The speed limit goes form 55 to 35 in less than 1000Fort There is about 100ft of 45.) at around 2:00 p.m. on weekdays, this is the time high school gets out. The police stand on Peachtree Industrial Blvd. clocking cars in the Northbound lanes. It is very hard to see from a long distance because they are generally on motercycles. They genrally step out onto the road and point you to the side.
