Interstate 95 in Maine - Speed Limits

Speed Limits

The Maine Turnpike had a posted speed limit of 70 mph in the early 1970s, but as Maine then had no law against traveling less than 10 mph over the posted speed, the de facto speed limit was 79 mph. In 1974, as part of a federal mandate, the speed limit was reduced to 55 mph, with a new law including a "less than 10 over" violation. In 1987, Congress allowed states to post 65 mph on rural interstate highways. Following the relaxation, Maine increased its speed limit. In May 2011, a bill was introduced to raise the speed limit from Old Town to Houlton from 65 to 75 mph. It passed, with Maine the first state east of the Mississippi River since the 1970s to establish a 75 mph speed limit.
