Speed limit on Maine Interstate Rte 95 is a constant 65 mph.except when passing through larger cities. This change is marked clearly and with red flagged limit signs. Enforcement otherwise in Maine starts at around 72 mph. Immediately when crossing the state border into New Hampshire the limit drops to 55, posted with one small sign on the right of the bridge marking the border. This is a four lane road at this section and actually widens to six lanes a few miles further south. I counted fourteen [14] NH State cruisers, last Veteran’s Day, lying in wait within the first half mile over the border. Usually fewer, but always four or five. So go from a comfortable 70mph to a strictly enforced 55 mph with no warning and get tagged.
