North Dakota Highway 13 has its western terminus in Emmons County with ND 1804 and travels east about thirteen miles before entering Linton and beginning a concurrency with US 83. This concurrency is entirely within the Linton city limits, and after the highway leaves Linton, ND 13 travels east to the McIntosh county line. About five miles east of the county line, ND 13 starts a concurrency with ND 3. This concurrency travels about ten miles east to Wishek, where the highways part and ND 3 heads south. ND 13 then travels about eleven miles northeast to Lehr. In Lehr, the highway serves as the southern terminus of ND 30. A short distance northeast of Lehr, ND 13 travels along the McIntosh-Logan county line for about nine miles before curving northeast and into Logan County.
