Hamilton Blvd just prior to St. Nicholas and Ryan the speed limit is 35 mph as marked by signs just to the bridge, after you cross the bridge
heading towards entrance to 287, the speed on Hamilton drops to 25 mph, the claim by South Plainfield Municiple court is that the area is residential, however on the opposite side of the same county road Hamilton Blvd, the speed is marked at 35 mph. I don’t think the NJ DOT
certified the speed change, otherwise the sign just before the bridge would also read 25 mph to give drivers fair warning. Once you go over the bridge it’s somewhat of a blind spot especially at night.
