North Dakota Highway 43 (ND 43) is a state highway located in extreme north-central North Dakota. It is about 23 miles (37 km) long and passes through Bottineau and Rolette counties.
ND 43 runs in a virtually east–west direction its entire length. Its western terminus is at ND 14 about 3.3 miles (5.3 km) south of the Canadian border and about 3.7 miles (6.0 km) north of Carbury. Shortly after the route begins, ND 43 enters Turtle Mountain State Forest, where the highway curves slightly but eventually straightens out again. In Roland Township, ND 43 passes south of Lake Metigoshe and crosses Oak Creek. About 12 miles (19 km) east of ND 14, ND 43 again passes through a small section of Turtle Mountain State Forest. Three miles (4.8 km) east of the state forest, the highway enters Rolette County. ND 43 travels on a straight east–west course for six miles (9.7 km) in Rolette County before it comes to its eastern terminus at U.S. Highway 281 (US 281) and ND 3, which run concurrently. The terminus is about three miles (4.8 km) south of the Canadian border and the International Peace Garden, and about nine miles (14 km) north of Dunseith, North Dakota.[2][3]
