On this map, Missouri's highways are divided into segments roughly one mile long. Each highway segment's color and thickness indicates the number of billboards within 1,000 feet of it. Three mile-long segments had more than 20 billboards: I-35 near the Kansas border, US-65 south of Springfield, and US-54 near the Lake of the Ozarks.
