Houlton, Maine

Houlton sits at the northern end of Interstate Ninety-Five, right on the Canadian border, and it got here by accident of geography. In eighteen oh seven, settlers from Massachusetts pushed into Aroostook County looking for farmland, and Houlton grew up around a mill on the Meduxnekeag River. The county seat was formalized in eighteen thirty-nine, and the town's real identity came from two things: potatoes and the border.

Aroostook County would eventually grow more potatoes than any other county in the United States, and Houlton's customs post became one of the busiest land crossings into New Brunswick. The interstate runs north to Houlton, making it the literal end of the road for Interstate Ninety-Five.
