North Dakota Highway 19 (ND 19) is an east–west route through central North Dakota. It runs from County Road 19 (CR 19) at the McHenry–Pierce county line to ND 20 in Devils Lake, a total of 70miles. It has one concurrency with US Highway 281 (US 281) for 4miles near Minnewaukan.
ND 19 begins at the McHenry–Pierce county line traveling east as a continuation of CR 19. The highway travels 2miles south of Battema Lake and 2miles north of Lesmeister Lake before intersecting with ND 3. After this intersection, the route heads northeast for two miles and forms the northern border of the Buffalo Lake National Wildlife Refuge, crossing Buffalo Lake in the process.
3miles after entering Benson County, ND 19 enters the small city of Esmond. After leaving Esmond, the route travels north for two miles. After turning east again for 11miles, the highway intersects with ND 30. About 12miles east of this intersection, ND 19 reaches the city of Minnewaukan and begins a 4adj=onNaNadj=on concurrency with US 281. During this concurrency, the route travels northwest for three miles, then due north for the last mile (1.6 km). After this concurrency, the highway heads east once more and crosses Pelican Lake before crossing Oswalds Bay and entering Ramsey County.
In Ramsey County, the route travels east and crosses Sixmile Bay and Creel Bay. ND 19 serves as the major route between the city of Devils Lake and Devils Lake Regional Airport. The highway intersects US 2 in eastern Devils Lake. Less than a mile farther east, ND 19 meets its eastern terminus at a junction with ND 20.
The majority of ND 19, the portion from its eastern terminus in Devils Lake to its junction with ND 3, was completed in 1939 and was the original alignment of the route. The small portion from ND 3 to its current western terminus at the McHenry–Pierce county line was completed between 1965 and 1975.
