North Dakota Highway 20

North Dakota Highway 20 (ND 20) is a 170.550 mi north–south highway in North Dakota. It runs from U.S. Route 52 (US 52) and US 281 in Jamestown to the Canada–United States border near Sarles. The highway continues into Manitoba as PTH 34.

A portion of ND 20 between mile markers 87 and 90 was closed in April 2010 due to flooding at Devils Lake and Spring Lake.
